The "DRI lockup on switching console back to X" I am seeing still occurs
with 2.4.19-pre10 plus the pageattr-B1-2.4.19-pre10 patch recently posted
to LKML by Ben LaHaise.  For the record, the other relevant details of my
system are a Radeon VE QY video card, Tyan S2460 motherboard (AMD 760MP
chipset) and RedHat XFree86-4.2.0-8.

On a similar system, replacing the motherboard with an ASUS A7M266-D (AMD
760MPX chipset) eliminated the lockup.  As both chipsets use the AMD 762
northbridge, I guess either the motherboards program the northbridge
differently, or else there is some interaction with the two different
southbridges (AMD 766 in 760MP, AMD 768 in 760MPX).
