Here's some correspondance between Donand Becker and myself. The problem is,
essentially, that this contains a programmable microcontroller. The Win98
driver probably programs it. Kawasaki supplied only electrical information
for it online. I'm trying to get more info from them. They wouldn't give it
to Becker, though, so I'm not hopeful (doesn't mean I'm not stubborn).
Follow-up:

The chip inside says "KL5KUSB101BCL"

Full chipset info, apparently!

Subject: NetGear EA101c USB to Ethernet
I bought a NetGear EA101c USB to Ethernet adapter today, intending to hook
it to an iOpener (http://www.linux-hacker.net/iopener/), which I special
ordered. I've done a little looking around, but I've not found anything
about Linux support for this gadget. With the aid of a screwdriver, the
Linux kernel and the net, I determined that it's really a LiteOn LNE100TX
ethernet chip inside. Unfortunately, I'm having trouble finding out anything
about that device, as well. What's the current state of USB to Ethernet
devices on Linux? If anyone knows anything about Linux ethernet drivers,
it's you, so I thought I would ask. If there's anything I can so to help as
well, let me know. Peeking through the files on the Win98 driver disk, I
found a few more bits of info:
NETEA101.INF:
%USB\VID_0846&PID_1001.DeviceDesc% = NETGEARUsbEth, USB\VID_0846&PID_1001
... Vendor ID 0846 and Product ID 1001, I assume
Opening the EA101ND4.SYS file up in Visual Studio, I found some more stuff.
CompanyName: Kawasaki LSI U.S.A, Inc.
ProductName: KSLI USB-Ethernet Adapter
FileVersion: 02.00 02.02
InternalName: USBENET.SYS
ProductVersion: 02.00 02.02
E:\SOURCE\Wolfe\NT50DDK\SRC\NETWORK\REESES\i386\free\USBENET.pdb
... wonder if it will work on 2000 as welll...
Looks like an NDIS driver...

LiteOn LNE100TX is a Tulip based adapter chip (perhaps an inferior copy)
see http://cesdis.gsfc.nasa.gov/linux/drivers/pnic.html and
http://www.linksys.com/support/solution/nos/linux_lne100tx.htm for
details.
Did you open the dongle? What else was in the dongle - some form of USB
microcontroller (Anchorchips maybe?) ?
I am not sure what you mean by "recognized it on boot". Do you mean that
some driver actually recognised the adapter? Or that the kernel knows
about LNE100TX (aka tulip)?
What boot (or dmesg or /var/log/messages) entries are applicable? What
drivers did you have loaded?
What does /proc/bus/usb/drivers and /proc/bus/usb/devices contain?
If it is a tulip based adapter, then the missing magic is in the USB
control/interrupt/bulk messages to LNE100TX part. As Vojtech pointed
out, this needs to be provided by the manufacturer. Or potentially
reverse engineered from Win98. Or maybe from the FreeBSD stuff, which
does have a wider range of ethernet USB adapters (probably not this one
though) than Linux.
Also, the NetGear website claims it is a 10BaseT device, although the
adapter should be 10/100 if it is really a tulip chipset.
