It worked fine with FreeBSD/PicoBSD, but ISA and PCI performance really sucked. I did not encounter any of the problems you have. Make sure of any BIOS settings that may cause problems, you may want to turn off cache to test that. Also you may need to check how the STPC chip and Super I/O chips are programmed, they may need to be reprogrammed to a setting that FreeBSD may work with better. We finally gave up on the STPC and decided to go with the AMD ELAN 410 chips we had better performance with them.
