Yes, just posted a Patch-For-Comments that switches on the availability of a TSC (tsc_init sets tsc_disable also for !cpu_has_tsc) which would mean that only really old stuff would be using the outb still. A TSC is really all we need to have a sensible udelay().
Uhm, no. You have no clue what the speed of the TSC is until you have been able to calibrate it against a fixed timesource - like the PIT.
