2.2.13 APM Resume Oops on Extensa 670CDT

[S Bond]

* Resume after Suspend results in an unrecoverable Oops.

* Standby works rather well.

* Searching the archives, I came across a related post, but unresolved
(?) post:
http://www.uwsg.indiana.edu/hypermail/linux/kernel/9907.1/0793.html

* Details:

My laptop is a TI Extensa 670CDT, running an upgraded version of RH6.1,
using kernel 2.2.13.

* I copied the following Oops from the screen after it locked on Resume
(hopefully I didn't introduce any errors when I copied it):

Code: <1>Unable to handle kernel NULL pointer dereference at virtual
address 00000000

Please CC any responses to me, as I tend to drop off the list from time
to time.

Thanks,
