Good to hear you're getting the same results!

Since you straightened me on what to expect, I went ahead and changed
the southbridge/i440bx to i82371eb, and recompiled all the 440bx targets
I could find (successfully, except that the eaglelion/5bcm tried to look
for a payload under /home/hamish, which for some reason didn't exist on
my system :-).  I've attached a patch for this - could you review and
commit for me?  I think it may require some svn magic to copy/remove the
old 440bx directory and files - I'm not sure how well just applying the
diffs here will work (I'm an svn newbie).

I'll tackle rebasing the RAM init on the e7501 next.

Thanks,

Don
