done.

I used the config file from Redhat.  It may be out of date for the
alpha on the SIS.

(mic:9) fgrep -i sis kernel-2.4.18-i686.config kernel-2.4.18-alpha.config

Based on this diff, looks like CONFIG_FB_SIS maybe should be set on
the alpha config.

I suspect these are an include file problem with the symbol versioning.

Thanks for the input!  The big question is should we fix these now,
or roll these fixes into the next build of a rawhide version?
