I've heard of several MTRR issues with 2.6.x, of which this is likely an instance.
The pattern seemed to involve attempts to cover the final portion of RAM with numerous fragments decreasing in size with ascending physical address, and failure to cover the final 4-8MB RAM. Odder still, the affected systems seemed to only have 1GB RAM, and for some reason 2.4.x was not affected.
I've walked about 3 or 4 users through manually correcting the MTRR settings over the past 2 weeks.
