Here's a /var/log/messages snippet:
AMD K7 CPU detected.
PowerNOW! Technology present. Can scale: frequency and voltage.
Found PSB header at c00e50e0
Table version: 0x12
Flags: 0x0 (Mobile voltage regulator)
Settling Time: 100 microseconds.
Has 1 PST tables. (Only dumping ones relevant to this CPU).
PST:0 (@c00e50f0)
cpuid: 0x780^Ifsb: 100^ImaxFID: 0x16^Istartvid: 0xb
FID: 0x4 (5.0x [500MHz])^IVID: 0x13 (1.200V)
FID: 0x6 (6.0x [600MHz])^IVID: 0x13 (1.200V)
FID: 0x8 (7.0x [700MHz])^IVID: 0x13 (1.200V)
FID: 0xc (9.0x [900MHz])^IVID: 0x13 (1.200V)
FID: 0xe (10.0x [1000MHz])^IVID: 0x11 (1.250V)
FID: 0x0 (11.0x [1100MHz])^IVID: 0xe (1.300V)
FID: 0x2 (12.0x [1200MHz])^IVID: 0xd (1.350V)
FID: 0x16 (14.0x [1400MHz])^IVID: 0xb (1.450V)
Minimum speed 500 MHz. Maximum speed 1400 MHz.
The values look correct for an AMD Mobile Athlon XP 1600+, don't they?
BTW, a patch for the patch.
Well, actually, for its comments: you wrote Mhz somewhere and MHz
somewhere else. The right symbol is MHz, always! ;-)
