Perhaps you could more fully leverage the various distro
alpha/beta/rcs/release kernels.

Specific to the PMP patches, they went into the openSUSE beta/rc
kernels (2.6.23 based) in early Aug. I think.  So they have already
been through a significant set of Novell internal and community
testing.  Likely similar testing to what it would get in -mm.

I believe they are part of the OpenSUSE 10.3 (2.6.23 based) full
release that is set for Thursday (Oct. 4) and thus will see a huge
amount of public testing.
