Your errors similar to things mentioned in this bugzilla entry,
means
with XKB?
That was it.
using Option "XkbRules" "xorg"
instead of Option "XkbRules" "xfree86"
did the trick.
I guess upgrading meant no xorg.conf file was written and the old XFree86CONFIG was used
instead but didn't quite work.
Anyway, thanks.
