It may be. When it breaks, what is the address it happens at?
When you say integrated S3 do you mean in the chip set? Does it used
shared memory?

The possible issues here are

1. the S3 is sharing the memory; there is no allowance for this, and
    when the buffer cache meets the frame buffer horrible things happen

2. which symbios controller? check that the PCI bus specs. match, as
    older symbios controllers don't work on newer PCI busses

If it is the scsi controller, and the bus specs. match, then I get more
interested, having written the symbios driver.
