[parisc-linux] hack to use HPUX boot loader

Probably not.  I applied som_relocate on the kernel that I built today and
it booted through the RAM disk phase on my 735 up to the following point:

bad address 0000001c (code 15)

Kernel panic: bad address

In swapper task - not syncing

Since I am booting with hpux, the early walk through the hardware
configuration scrolls off the screen.

I have had to patch the Makefile to build with gcc 2.95.1 and without GECKO.
Can someone install this patch in the cvs source?

Dave
