Keyboard nuts after APM suspend/resume on Thinkpad R40

Description of problem:
This is on an IBM Thinkpad R40 with Intel Corp. 82801BD PRO/100 VE
(MOB) Ethernet Controller (rev 81) [e100 driver], and Intel Corp.
PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04) [ipw2100-1.0.0
The machine is rock-solid with 2.6.8-1.521, and suspends and resumes
cleanly using APM.
With 2.6.9-1.3_FC2, suspending didn't work unless the wired ethernet
interface was taken down; resuming would result in the keyboard
producing seemingly random characters. With 2.6.9-1.6_FC2, the
machine now suspends cleanly in the same situation, but the keyboard
is still unusable after a resume.
Let me know if you need any further information.

Steps to Reproduce:
This seems to be fixed as of 2.6.9-1.724_FC3.

I was overly optimistic. The problem did not occur during the first
suspend/resume cycle with 2.6.9-1.724, but reappeared with all future attempts
to suspend/resume the machine. I'm back to a custom version of 2.6.8.
The workaround suggested in comment 142329#c11 (adding atkbd.reset to
the kernel command line) seems to cure the symptoms. I'll report back
if the problem reappears.
This problem does not occur any more with 2.6.10-1.737_FC3, regardless
of the atkbd.reset kernel parameter. With that kernel, though, the
machine crashes as described in bug report 145203.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
