sun4m and 2.4.x revisited

[Simon Read <simon@formasic.com>]

Folks,

I have two questions:

What  about the 2.4.x  kernels is  wrong that  they don't  function on
sun4m?  Is  this problem a  simple build fix (wrong  headers, compiler
options, &c), or does it require major software writing?

Does the kernel at vger.samba.org differ  from the one that we have in
2.4.7?  Does that kernel correctly support sun4m?

I have a single SS20 which is an important part of my network.  I want
to upgrade it to  a 2.4.x kernel, and if a small  amount of extra work
would fix the problem in the  distribution I'd be willing to do it.  I
simply don't have time to get into major kernel development though.
