excellent. ;) 
might make a 'README.upgradingfromKludge'
I was thinking for a few seconds that it had broken swsusp entirely,
but it turns out I had a check in there that if radeon was in use it
should abort. ;)

yep. If I start another X server it works fine, or restart that one,
but in the one that was going over the suspend it doesn't work. 
No errors, and it seems to detect it like it's still there, but it
doesn't display anything.

anytime.
