Hmm, I guess I indeed better keep it: without it I have this liin in dmesg: warning: no time-of-day clock registered, system time will not be set accurately Also, in the Misc. section, "device iicbus" actually required for snd_ai2s. Not sure about "device kiic": it seems that Keywest I2C controller is fine with just iicbus: iichb0: <Keywest I2C controller> mem 0xf8001000-0xf8001fff irq 42 on unin0 iicbus0: <OFW I2C bus> on iichb0 iicbus0: <unknown card> at addr 0x1c0 I haven't looked into what is this strange "unknown card" yet, but adding or removing "device kiic" from kernel config does not change dmesg output. Source code for /sys/powerpc/powermac/kiic.c says it's some support routines for the controller; not sure if I need them on G4 or not. Is support for Keywest I2C controller is incomplete without kiic? Thanks, ./danfe
