RE: Fix for -psb X issue
According feedback from TG, it is not a bug for xserver 1.3, it might be compatibility issue for 1.4, currently they are not supporting 1.4 and they are not going to integrate patch into their source code.

Re: Fix for -psb X issue
Odd, I would have thought that since they have added requirements for xserver 1.4 features (EXA 2.2), that the code would have been tested against and supported on xserver 1.4 as well. But thanks, this seems to explain the origin of the problem.

RE: Fix for -psb X issue
Can you see where (e.g. with a calltrace) the first lock happens and where the second lock happens?

[1] Yesterday, Amit and I found that a psbDRILock() routine was being called twice; this routine requests a lock in the kernel, which works the first time, but not the second. So this morning, I disabled the second lock/unlock in -psb[2], and sure enough, X came up and seems to be working as expected now[3].
