PCI card, eh? (Heh. In writing my previous mail, I think I even wrote 
"These are clocksources soldered to the motherboard, not pci cards!", 
but deleted it as it didn't seem useful. :)

So I think that's actually a first for clocksource drivers.

So, if there are genuinely cross-architecture pluggable clocksources, 
that aren't part of a platform definition, I would be ok with making an 
exception. But I'd want to make sure that we kept a high-bar for adding 
clocksource options, so that folks don't just clutter up the Kconfig menu.

That said, Daniel (now cc'ed - sorry for not cc'ing you earlier!) is now 
in charge of the clocksource directory, so my objections and wishes 
aren't as important as his.

thanks
