Default ACPI with new legacy release 96.43.01 still doesn't work

I just made a test of the newly released driver 96.43.01 since none of the 96xx (xx=25, 26, 29, 31, 39) did allow ACPI to work reliably on my laptop, a DELL Latitude D800 with a GeForce4 Ti 4200 Go card (i386 pentium M processor) and Ubuntu Feisty Fawn 7.04 (kernel 2.6.20).

The problems reported in my previous messages (see threads 82507 and 95755 on this forum),
also confirmed by other people, remain unsolved.

The older drivers from the 8xxx series work, however. I am thus held back to 8776 (which is unfortunately not as capable as far as 3D Desktop
is concerned). The problem seems to boil down to routines related to switching virtual
consoles. Here is a typical situation which makes everything hang (requiring afterwards a hard reboot):

normal kdm session (opening X :0 vt7)
chvt 1
chvt 7
X :5 vt12 (as super user) --> everything freezes

Switching vt's at least one time as indicated is "necessary" to get the freeze. Changing vt12 to anything else than vt7 produces the same effect.

Without performing explicitly the chvt trick, the freeze also occurs when calling e.g. a 'X :5 vt12' session, killing it and calling it again - a switch of vt's realized by any means seems to produce the bug.

All this prevents using drivers 96xx for anything else than a single session - more severely it also limitates suspending the laptop to RAM or hibernating - as switching vt's is needed in the process. (I succeeded to suspend and resume several times by removing the switch of virtual consoles in the ACPI scripts, but then the screen becomes more and more corrupted and is completely unusable after 2 or 3 times... leaving the X :5 vt12 open and switching between vt7 and vt12 also works somehow and is the only (ugly) work-around I found with 9639).

I enclose my nvidia-bug-report.log below.

Best regards,

Jean-Pierre Demailly
