I booted Windows 2000 on the 600E and it comes up in ACPI mode
w/o getting confused by this broken DSDT.
Curiously it moves yenta and USB on IRQ9 along with ACPI:

1       Standard 101/102-Key or Microsoft Natural PS/2 Keyboard
3       IBM ThinkPad Fast Infrared Port
4       Communications Port (COM1)
5       ThinkPad Modem
6       Standard floppy disk controller
7       Crystal WDM Audio Codec
8       System CMOS/real time clock
9       Crystal SoundFusion(tm)
9       Intel 82371AB/EB PCI to USB Universal Host Controller
9       Intel(R) PRO/100 CardBus II
9       Microsoft ACPI-Compliant System
9       Texas Instruments PCI-1251 CardBus Controller
9       Texas Instruments PCI-1251 CardBus Controller
11      ThinkPad Digital Signal Processor
12      IBM PS/2 TrackPoint
13      Numeric data processor
14      Primary IDE Channel

Linux in acpi=off doesn't move IRQs and it finds these on IRQ11 --
which means that W2K somehow picked them up and moved them.

  1:         10          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  6:          5          XT-PIC  floppy
  8:          1          XT-PIC  rtc
 11:        326          XT-PIC  uhci_hcd:usb1, yenta, yenta, eth0
 12:        110          XT-PIC  i8042
 14:       3218          XT-PIC  ide0
NMI:          0
ERR:          0

Booting Linux with the DSDT fix in ACPI mode also finds
these links and these devices on IRQ11:

ACPI: PCI Interrupt Link [LNKA] (IRQs 3 4 5 6 7 9 10 *11 12 14 15)
ACPI: PCI Interrupt Link [LNKB] (IRQs 3 4 5 6 7 9 10 *11 12 14 15)
ACPI: PCI Interrupt Link [LNKC] (IRQs 3 4 5 6 7 9 10 11 12 14 15) *0, disabled.
ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 6 7 9 10 *11 12 14 15)
           CPU0
  0:      21324          XT-PIC  timer
  1:          8          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  4:        448          XT-PIC  serial
  8:          1          XT-PIC  rtc
  9:        310          XT-PIC  acpi
 11:        232          XT-PIC  uhci_hcd:usb1, yenta, yenta, eth0
 12:        153          XT-PIC  i8042
 14:       3478          XT-PIC  ide0
NMI:          0
LOC:          0
ERR:          0
MIS:          0

I can't explain how W2K does this.  It couldn't possibly have
used the ACPI PCI Interrupt Links with the bad ISA0 address --
unless it has some platform-specific workaround.  Perhaps it
sees that the Links are not working and silently falls back
to legacy PIRQ routing. Unclear that any of the other AML
in the DSDT besides the links will fail due to the bad
PCI devnum.  First glaces shows just IO space accesses,
so maybe the other things under ISA0 are okay with the
broken DSDT.
