---end dmesg snippet---...and on and on the dma errors go.
This occured about (sorry, not sure exactly, but I don't think it quite
matters with this particular error) when I used "iwlist scan" to search for
wireless networks after I used the b43-fwcutter from Debian testing to
install the firmware and re-inserted the driver with 'modprobe -r b43;
modprobe b43'.

As you can tell, this processor is neither an Atom nor a ULV Core 2 Duo.
The WLAN card is the Dell Wireless 1395 that came with the laptop (a Vostro
1510). I can build a custom kernel based on the Debian kernel sources if
need be; just tell me what config options to flip/patches to apply. Also,
wl.o works on this laptop with the Debian 2.6.30 kernel. Aptitude lists the
kernel version as a 2.6.32-5.
