fbdev problems

Hi,
eventually I managed to get tvout working with my ATI rage 128 rf/sg
using
the vesafb kernel driver and boot option "vga=0x315". Even mplayer
works fine
with -vo fbdev.
Hoever, I can't get X11 up and running. It bails out with

I have tried turning ShadowFB off and disabled all modules in
XF86Config-4
but no change...

Any ideas?

TIA, Chris.

Adding "DefaultFbBpp 24" to the "Screen" section and running with 32 bits
depth ("DefaultDepth 32") solves this problem which is apparently caused
by X identifying the packed pixel mode wrongly as either 24 bits when
requesting 32 but can't operate with 24 bits because it's packed pixels.
(IOW "DefaultDepth 24" does not work in this setup.)

Now, tvout works like a charm.
