Here it compiles and boots ok (SMP disabled, only generic SCSI support)
and the Cyclades PCI cards are detected (hey, Martin, your port works fine
!!!! :). There are some more changes in the Cyclades driver to be added,
but this is probably being submitted for 2.1.94 (right, Randy ??? ;).

But ... the /proc filesystem does not seem ok. Even though the /proc/pci
is there ...

debiandev:~# cat /proc/pci
PCI devices found:
Bus 0, device 0, function 0:
Host bridge: Intel 82437VX Triton II (rev 2).
Medium devsel. Master Capable. Latency=32.
Bus 0, device 7, function 0:
ISA bridge: Intel 82371SB PIIX3 ISA (rev 1).

<snip>

I/O at 0x6200 [0x6201].
Non-prefetchable 32 bit memory at 0xe0200000 [0xe0200000].
debiandev:~# cat /proc/bus/pci/00
cat: /proc/bus/pci/00: No such file or directory
debiandev:~# ls /proc/bus
debiandev:~# ls /proc/pci
/proc/pci
debiandev:~#

If I go back to 2.1.90, everything is ok (both /proc/bus/pci/00 and
/proc/pci are present).

Comments ???
