The bug is perfectly reproducible on a system with such a BIOS (for instance ASROCK 939A785GMH).

With RAID disabled the RAM is free up to about 0x9f800 (displaymem in GRUB and lsmmap in GRUB2), with RAID enabled a reserved area appears at 0x92400 (len 0x0dc00).

The bug was mentioned long ago somewhere on the internet also in relation to memtest, but I believe any kernel with bzImage format (which an old file was documenting that it gets loaded in that area) will trigger the problem.
