Hmmm, looks like this is a widespread problem.  I have the same card in a
Toshiba Tecra M1:

01:00.0 VGA compatible controller: Trident Microsystems CyberBlade XP4m32 (rev 91)

I get the blue colour too, although I can change it with xvattr (its the
XV_COLORKEY).

xvinfo says that xv is working, I can hear sound with mplayer, xine, mythtv etc,
as the system doesn't crash, but only the blue screen is seen.

This is a pity - everything else works fine - which is pretty good given I
understand Trident haven't been too helpful.

I've tried everything I can think of in xorg.conf, no acceleration, shadowFB on,
off, bit depth 16, 15, 24, etc etc etc.

This is on Mandrake 10.1 (kernel 2.6.8.1), running the thac rpm (x.org 6.8.2,
patch level 6).
