FWIW I'm using both INT0 and INT1 on M168 with no problems ... now. I did 
spend several hours banging my head against these interrupts because a) I'd 
used the wrong vector names; b) more than one of the bit defs in the 
avr-libc headers were wrong. The latest WinAVR appears to correct the bit 
defs but it sounds as though you're using asm anyway?
