Only those which I listed in my earlier mail plus the following list: --- propietary 2007-09-01 20:21:24.000000000 +0200 +++ lb 2007-09-01 20:21:24.000000000 +0200 switching to LDN 0x2 (serial port 2) idx 30 60 61 70 -val 00 00 00 00 +val 01 02 f8 03 prop disables com2 an clears baseaddr+irq.

Fix the issues mentioned above as "FIX" and post another probe_superio from a lb boot after fixes.
