hmm, haven't noticed that!

here's the try:
[root@vbox4 ~]# modprobe ipmi_si type=kcs addrs=0xca2 regspacings=1 regsizes=1 regshifts=0 irqs=0 slave_addrs=0x0

dmesg:
[33743.684605] IPMI System Interface driver.
[33743.684607] ipmi_si: probing via hardcoded address
[33743.684608] ipmi_si: Adding hardcoded-specified kcs state machine
[33743.684610] ipmi_si: Trying hardcoded-specified kcs state machine at mem address 0xca2, slave address 0x0, irq 0
[33743.684612] ipmi_si: Could not set up I/O space

cheers!
