kernel26mm is now updated to version 2.6.22.rc2.mm1-1, and is accompanied by a total of two external module packages - ipw3945-mm and lirc-mm. nvidia and fglrx do not build against this kernel, nor do many of the networking module packages, although some of them are now included in -mm e.g. the rt2x00 wireless drivers.
Given -mm's volatile nature, I don't intend to search for, or create, patches for any of the failed builds. However, if others are inclined to do so, I'll be happy to incorporate them.
All the best Tom.
