i've got this running on my laptop but i'm not using it very heavily
however, i did see a problem with this patch on a different system
i meant to tell you about... ah, good, the console log is still handy:
radeondrmkmsfb0 at radeon0
radeon0: info: registered panic notifier
wsdisplay0 at radeondrmkmsfb0 kbdmux 1
panic: kernel diagnostic assertion "l->l_exlocks == 0" failed: file "/usr/src5/sys/sys/userret.h", line 87 53 exlocks held

i didn't look any further right then, i just reverted the patch.
config options appear to be just DIAGNOSTIC and makeoptions DEBUG.
