Reserved pages not flagged on Compaq evo?

[Michael Frank]

A 2.4.24 + swsusp 2.0 user reported a mce at the video base address
of 0xa0000 when writing the kernel image to disk (thus reading there)
on a Compaq evo1015v (Athlon XP 2000+)

NOMCE eliminates the mce but I am wondering about possible ill effects
should other reserved pages be invalidly accessed.
  
It looks like these pages are not flagged reserved and therfore accessed. 

No other mce's have ever been reported.

What is the suggested approach to identify the root cause?

Michael
