With the new 2.6.35-25.44~SPC01LP703553 package installed, I can confirm that the graphics failed as they did with the original 2.6.35-25.
I'm assuming that this package replaces the stock 2.6.35-25 in the grub menu with the new version - it didn't show up separately as the mainline kernel image did. Sorry if this is obvious - I don't normally change the stock kernel!
