Using this, 2.3.28 boots a bit further. It locks up right before the SCSI
device probing. After `scsi : 2 hosts.', I can still toggle the Caps Lock LED
for one second, but after that interrupts no longer seem to come through.

    ncr53c8xx: IO region 0x1400 to 0x147f is in use
    mesh: assuming 50MHz clock frequency
    scsi0 : sym53c8xx - version 1.3c
    scsi1 : MESH
    scsi : 2 hosts.

Fortunately the kernel gets sufficiently far to resume working on frame buffer
device, cfr. the patch I just posted.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
