[PATCH][RFC] sort out CLOCK_TICK_RATE usage [0/3]

[Thorsten Kranzkowski]

Hello!

With every 2.6 kernel I tried the system speaker on my Alpha produces a 
rather unpleasant high pitched tone instead of the normal system beep.
This is because in p|cspkr.c the calculation of the counter values is
incorrectly based on CLOCK_TICK_RATE. 
To solve this problem I came up with these tree patches:

1/3:	introduce PIC_TICK_RATE constant. It seems this is not always
	the same value.
2/3:	use PIC_TICK_RATE in *spkr.c and some other places where the
	PIC is directly programmed.
3/3:	use CLOCK_TICK_RATE where 1193180 was used in timing calculations.

Tested on Alpha, compile & boot-tested on i386 (unrelated LVM problems here)

Arch maintainers please have a look whether I got the constants right or
if your architecture has a PIC at all.

Comments welcome.

Bye,
Thorsten
