I do not support any distribution packages, as i have no way
to tell what they modified.

I'm not sure whether the current svn HEAD compiles with such
an old kernel. And even if it does, there was at least one
incompatible API change from 2.6.26 -> 2.6.27.
The effect can be seen at:

This is part of an Oops message, that you should have seen
if you had checked the output of dmesg.

Your options are:
1) try the mga_vid version for 2.6.26 (no idea whether this works with .24)
2) use the mga_vid version for 2.6.24, but make sure that you have the
   correct mga_vid.h used by your player application (with mplayer svn,
   you need to copy the mga_vid.h from mga_vid into the mplayer source tree)
3) upgrade your kernel

I'd recommend 3)

Note: i haven't tried mga_vid with 2.6.28 yet and i'm probably not able
to do so for the next few weeks. If anyone could confirm whether mga_vid
works/doesnt work for 2.6.28, i'd appreciate that.

Your signature is way too long, please trim it to 4 lines
as defined by the netiquette.
