Looking for a small linux distro that supports many architectures

[Michael Blandford <mlblandf@sedona.ch.intel.com>]

Hello,

I hope this isn't too off topic for this list.

I am looking for an extremely small distro that I can net boot on 
multiple architectures.

The debian-installer seems to be the closest thing I have found.

I am looking to support ia32, ia64, sparc, and HPPA.  The first two 
would be a priority.

What I am hoping for is a distro that could boot up, do all the hardware 
detection and module loading, and then return control to another program 
( versus loading a new OS ).

I would need to inject a few additional programs into the image to make 
things work.

Does this seem like something I could do with the debian installer?  If 
so, could I get some pointers on where to start?  Debian is not a distro 
I am terribly familiar with.

Thanks,

Michael
