I tried it on an iBook late 2004 and it works (same cpu type as PBooks):

cpu0 at mainbus0: Version 0x8003 (Revision 0x0102), ID 0 (primary)
cpu0: HID0 8410c0bc<EMCP,EICE,DPM,ICE,DCE,SGE,BTIC,FBIOB,ABE,BHT>
cpu0: 1203.71 MHz, 256KB L2 cache

I'm about to try Michael's experimental thermal drivers to see if 
temperature would be kept at bearable levels.

best regards (sorry for my poor english :( )
