SAFARI config register address

	Hello,

	Since NetBSD is stable on my Blade2000, I'm trying to add cpufreq 
capabilities. CPU clock (on US-III) can be divided by 1, 2 or 32. This 
divider is controlled by a value set in SAFARI config :
- 0x0000000000000000UL => /1
- 0x0000000040000000UL => /2
- 0x0000000080000000UL => /32

	For US-IIe, clock can be divided by 2, 4, 6 or 8, but is controlled by 
ESTAR mon control register. I shall patch kernel in a second time as I 
have to reinstall my Blade 100.

	I'm working on 7.99.1 kernel and Schizo register are defined in 
schizoreg.h. I suppose I have to use schizo_write() and schizo_read() to 
modify this value, but I don't know safari config register address.

	Any idea ?

	Regards,

	JKB
