X-windows starts, but the picture is horribly torn, only the grey stipple
pattern is recognizable.  Any thoughts?  Or should I start a binary
search for the last version that worked?

Thanks, Duncan.

Strange, and this only happens when you have agpgart loaded ?

I believe I sent a similar mail to the list a week or so ago.
I'm experiencing troubles with KT400 when built as a module
and compiled in. The exact troubles depend on the kernel version.
2.6.54 will fire up but hang as soon as I fire up any GL application.
2.6.55 will eat endless amounts of memory when loading the module
thereby bringing the machine to crawl.

It was a BIOS problem: I flashed it, and the problem has gone
(the agpgart: Putting AGP V2 device at 00:00.0 into 1x mode
messages have gone too).  The strange thing is, there was no
problem with 2.4 even before flashing the BIOS.

All the best,

Duncan.

It was not a BIOS problem.  I just went back to an earlier BK tree
and the problem reappeared.  I must have updated the BK tree
between tests.  Sorry for the misleading information.

	The default agp speed  in X's radeon driver is 1(cvs from serveral
days) , and seems that X sets that mode. I may have a BIOS problem too
after boot agp speed is undefined, when set to 4 in bios, but in  Option
"AGPMode" "4" changes this, radeon 9000 , kt133 all ok, haven't digged furter.
I've looked at agp changes and this message was added soon there, so this 1x 
may be there from a long time. You can check what the mode is with lspci -vv
too, i've not tested with 2.4, but suspect that you'll see 1x there too.
