Hi all,
I just upgraded to 8.44 and also had that PreInitDAL problem (magically fixed after restarting X), but on my gentoo computer it's another error which prevents my 3D acceleration from working: (2D accel works)

I'd also add that everything worked with 8.43 before.

I'm using an X1600 Pro by Saphire, 512 MB and an AGP card.

Any ideas on how to fix that?
Many thanks in advance.
