At this moment I do not see how to get around the following
kernel code in sys_dp264.c:

static void
dp264_device_interrupt(unsigned long vector, struct pt_regs * regs)
{
#if 1
        printk("dp264_device_interrupt: NOT IMPLEMENTED YET!! \n");
#else
...
#endif
}

which will stop you dead on boot.  This code is NOT in an execution path
when you are booting from SRM.  Well, maybe (a BIG maybe) it will be not
executed if you do not have any IDE devices, like CD, as well.  Or you
may play brave, change that '#if 1' to '#if 0' and watch fur fly. :-)
I really have no idea what such change will do to your hardware - maybe
nothing bad.  But I would suspect that it was left there because some
essential issues were still unresolved.  Jay?

BTW - this gotcha has a totally non-existent association with RH 6.1.

It is pretty weird to have SRM for a board which does not support
this board buil-in hardware.  Sigh!
