it comes with recent svgalib. but be warned, it contains a very stupid
vulnerability that lets any user with access to the helper access all
of kernel memory read/write.. someday i'm gonna submit a patch.

just curious...what card was this? maybe you mentioned it in another
email but if so i forgot.

depending on how long ago this was, maybe mplayer did software-scaling
with -fs by default in some vo's...

you're right, it is a strange speed. afaik it was overclocked. the
highest speed available for most k6 processors was 450. one model also
had a 500mhz version, but that was rare. so i expect whoever sold it
to you overclocked it (or lied about its speed so you would overclock
it yourself).
