Check to see if your e820 map has a hole in it, and whether any of your Cardbus bridge memory / region 0 resources appear in it.
If your e820 map contains a hole, I'd suspect another buggy bios.

Is the hole between 0x36f6fa000 and 0x3f700000?
And what would be the proper way of fixing it (assuming that IBM won't issue a fixed BIOS)?
