Or there is something I don't catch about mtrrs, or it still does silly
things.

I have an ASUS PCDL, dual xeon, 2Gb of memory. Mtrrs after cleanup are:

werewolf:/proc> cat mtrr
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
reg01: base=0x40000000 (1024MB), size= 512MB: write-back, count=1
reg02: base=0x60000000 (1536MB), size= 256MB: write-back, count=1
reg03: base=0x70000000 (1792MB), size= 128MB: write-back, count=1
reg04: base=0x78000000 (1920MB), size= 64MB: write-back, count=1
reg05: base=0x7c000000 (1984MB), size= 64MB: write-back, count=1
reg06: base=0x7ff00000 (2047MB), size= 1MB: uncachable, count=1

So it adds a last WB zone, but substracts the last 1Mb. (Why do
I have that stupid uncacheable mb ? probably a bios issue...)
But those two 64 mb zones could be add to a 128Mb, that new one
with previous to 256Mb and so on, giving something like:

reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x7ff00000 (2047MB), size= 1MB: uncachable, count=1

Is this incorrect ?
