The 486DLC will (barely) work with various levels of success, depending upon
what sort of I/O you are using. I managed to bring up a 1.1.5.1 system long
enough to write patches and build a new kernel with DLC support.
FreeBSD 2.0 recognises the DLC and does the right things (idea & original
code courtesy of NetBSD).

p.s. any netbsd folks out there: you also want to flush the cache any
time the CPU goes into hold state -- this will hopefully cover
dma's outside the 640k-1mb range.
