xorg-7.3 and gdm

[P.U.Kruppa]

Hi,

after upgrading to xorg-7.3 some drivers don't seem to work 
anymore. A simple
# startx
will result in
 	------------------------------
[...]
(EE) module ABI major version (1) doesn't match the server's 
version (2)
(EE) Failed to load module "s3virge" (module requirement 
mismatch, 0)
(EE) No drivers available.
[...]
 	------------------------------

On some gentoo mailing list I found I can start X by
# startx -- -ignoreABI
which of course only starts xorgs twm window manager.

How can I pass this to gdm?
I tried to play around with /usr/local/etc/gdm/custom.conf
but all I get are segmentation faults.


Greetings,

Uli.
