APM bug with Inspiron 5000e

[volodya]

I am seeing this bug with both test8 and test12 kernels. Help/suggestions
for debugging are appreciated.

Computer: Inspiron 5000e. 
Bug: oops when doing cat /proc/apm.

Ask Dell for a working BIOS. This 5000E is a known BIOS bug.

What's the BIOS revision it claims to have during POST?  It should be
A0x (where x is a number).
