Ok, here's the patch again against what's current in the BK tree. I
just checked that it still applies and works with 2.4.22.

In the meanwhile I have verified that Radeon 9[578]00 cards also work.
(ATI's drivers).
Question for the list: the machines where I'm testing this have 4GB of
RAM. The MTRRs look like this after starting the X server:
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg02: base=0xc0000000 (3072MB), size= 512MB: write-back, count=1
reg03: base=0xd8000000 (3456MB), size= 128MB: uncachable, count=1
reg04: base=0x100000000 (4096MB), size=4096MB: write-back, count=1
reg05: base=0x200000000 (8192MB), size=8192MB: write-back, count=1
reg06: base=0xe0000000 (3584MB), size= 128MB: write-combining, count=1
reg07: base=0xf0000000 (3840MB), size= 64MB: write-combining, count=1
6 and 7 are set up by the X server. Originally 6 and 7 were two big
(16 GB and 32 GB) areas (at 0x400000000 and 0x80000000). After
removing those by hand and starting the X server AGP works (in case of
the ATI drivers, the X server won't even come up if AGP can't be
enabled).
The question is what are those areas for? (I mean 4 and 5 and the
original 6 and 7) There's no physical memory there...
TIA,
Marcelo

I am sorry, I just noticed I omitted the diff of the include/linux
directory. The missing bits are attached. The whole patch is
available from:
