Against linux/kernel/git/torvalds/linux-2.6.git?  Will do that tomorrow...  Grant, do you need a patch against Linus' tree, or against a released version, or against your tree?

Dumb question: do you use U-Boot to boot your processor?  If I interpret the code [1] correctly, it also uses the /16 prescaler!  Or did I miss something?

Best, Albrecht.
