Hi Geert!  Long time no see.

I poked around a bit and found a giant patch against 2.1.124.  It's..
not pretty.  It's ~95k uncompressed so I didn't want to send it to the
list, but fpaste seemed to take it:

  curl -o linux-next-2.1.124jes-18101998.patch \
	http://paste.fedoraproject.org/162196/27497714/raw/

I'm struggling to remember those few months that I spent hacking on the
NeXTs :).  I think most of it was blind stabbing in the dark while
comparing with open code sample and header files.. netbsd, some boot
loaders maybe, that kind of thing.  It got to a point where interrupts
and dma were working enough to tftpboot from the network.  But then I
got to the scsi part and.. I think it had endian flipping in the busses
somewhere?  That's when I moved on to some other weird project
(beboxes?).

I'm happy to try and help if anyone actually works on this.  I probably
wouldn't succeed, but I'd try.
