Heh, took me a minute to find.  I first found the one at
http://people.freebsd.org/~jhb/patches/pat.patch
but it maps devices as write-back.  I'm guessing you mean to use the
version in perforce?

I'll give it a try tonight.  Could hardy make things worse -- I just
noticed that X now randomly locks up hard, ever since I bumped up the
memory from 256Mb to 2G -- though text mode still works fine. (yes, I
tried reverting all my local patches and testing the memory)
