What X server are you using?  If you're using an old version of XFree86,
try upgrading to the current version:  XFree86 3.3.1.

If you're already using XF86 3.3.1, a quick look at the docs for Cirrus 
cards at http://www.xfree86.org/3.3.1/cirrus.html (more specifically 
http://www.xfree86.org/3.3.1/cirrus7.html#7 ) give a couple options
to help "jitter" and "wavy screens".  Have you tried those?

Do you have the info you found on this problem?  I'd like to look at
it since I have that same SCSI card in my PC at work.  Thanks.
