That didn´t really work, although it seems that it the missed keypresses 
 happen not so often. ( imagination? ;-)

a SiS650 in a MSI Hermes 650, same behaviour on a Intel845 ( MSI Hermes 
845GL )

Thats strange, and maybe the point to look at. Why needs the DVD Plugin 
20-35% on my system with Celeron 2000 ?!?
The DVD-ROM is attatched single at a IDE-Port.

I have gcc 3.3, glibc 2.3.2, kernel 2.4.20 ( SuSE )
