My general rule when naming interrupts is to have the names be similar
to what is printed out in the startup messages.

In other words, i think you'd probably want them to be called
something like "irq*" and "f(ast)irq*".  Unless i'm mistaken, there's
no difference in the way the fast and non-fast IRQ's would be printed,
so the latter is just a suggestion.  (However, i do think that 'irq'
is appropriate, somewhere in there.)

Yes.  And, the sort of sad thing is that it's not even very hard to
implement, for somebody with a reasonable knowledge of i386 assembly.
(I.e. enough to write the few lines of code in assembly to increment
the counters.)

I found it sort of amusing that in the time that that bug came into
existence before the Alpha port was even _started_, and the Alpha port
has had functional interrupt counters for a while now...
