RTC is available (and used) as of kernel 2.6.15 . The thing that has
changed in 2.6.13 is that the default of HZ became 250 (but still
tunable). So unless you build your own kernel, without using RTC you
would not really get a steady rate of 1000 interrupts per second.
And then again, on kernels >= 2.6.22 you have hi-resolution timers which
generally work better.

And if using something other than RTC: 1000 interrupts per second.
Anyway, "close to 1000" is easy to spot there.
