Why, yes it is.  See the ATtiny11 for a different scheme. :-(
And frequency will be dependent on things like temp and supply
voltage, which can be controlled to some extent, so the freq
may not be as variable as the spec sheet (must) imply.

I think so.  The 10F claims a 'precision' internal clock, like the
12f675, which is distinct from the simple 4MHz oscillator of the 12c508.
I think microchip got a message that people wanted the internal clock
to be good enough to do rs232...
