My experience with Cirrus Logic cards has been so horrid that I never use them
any more.  And I don't mean with Linux.  I have been reproducibly crashing
windows from driving Cirrus Logic cards to their rated potential.  I do of
course like Linux better than Windows because I can look with fair assurance
at a problem and start shifting hardware, because that is the likely area of
problem.  XFree, well, it has its problems, usually soluble in the config
file, but the one card I have always had difficulty (well, two) with are
Cirrus Logic and Paradise (the old WD 9002 chip).
