In a nutshell, the differences are numerous but largely minor (e.g., the 8259s needs to run in level-triggered mode as opposed to edge). These differences between ISA and MCA are enough to keep a stock kernel from running [properly] but shouldn't be prohibitive to change. I think I have an MCA 386SX machine sitting around somewhere.
