At least for gdm I don't think this will help because gdm startup fails
(reproducable or never) independently on whether the module was
previously loaded. So eventually this is some kind of a race condition
for kdm:
* the timeout is just sufficient
- if the module was previously loaded
- to load the module and initialize the card if nothing else eats cpu
time
* the timeout is insufficient
- to load the module and initialize the card while many parallel
startup operations happen because fewer cpu operations (I don't want
to say 'time' here) are available
- on slow systems (e.g. slow I/O (DVD) or emulated as Josef Spillner
reported) that don't get enough cpu operations for initialization
while the wall clock time runs at full speed.
