I think it will do the same as "5 1 gpio! 1 ms" in OF, but of > course, no warranty for that :) It didn't burn the PowerBook :) FreeBSD 8.0-CURRENT #8: Mon Nov 3 07:56:10 CET 2008 andreast@wolfram.andreas.nets:/usr/obj/export/devel/fbsd/src/sys/ANDREAST cpu0: Motorola PowerPC 7447A revision 1.1, 1504.63 MHz cpu0: L1 I-cache enabled, L1 D-cache enabled cpu0: 512KB L2 cache cpu0: HID0 8450c0bc<EMCP,TBEN,NAP,DPM,ICE,DCE,SGE,BTIC,LRSTK,FOLD,BHT> cpu0: HID1 8000fc80<EMCP,PC1,PC2,PC3,PC4,SYNCBEI,ABE,res> real memory = 1063473152 (1014 MB) avail memory = 1027330048 (979 MB) Thanks a lot!
