There are *lots* of changes between the working one (2964) and the one you 
used (3092):

http://sourceforge.net/apps/trac/unattended/changeset?new=3092%40trunk%2Flinuxboot%2Fmisc%2Flinux-config&old=2985%40trunk%2Flinuxboot%2Fmisc%2Flinux-config

In the meantime, I will start with a git-bisect-style process.  As you can 
see, I'm building kernel 2.6.38.5:


[root@openinstall linuxboot]# grep ^linux= Makefile
linux=linux-2.6.38.5


First, download config version 3068:

[root@openinstall linuxboot]# svn up -r 3068 misc/linux-config
U    misc/linux-config
Updated to revision 3068.


I build a CD, and hold down the <ENTER> key for a while when it's running 
Kconfig...

(I also have to do my magic to make DOSEMU compile.  Is there a way to 
remove this from the Makefile completely?  I'm not even using it!)

Boot it on all three machine types I have and it works!  So, next config: 
3089.  It too works!  However, 3090 *FAILS*.

I have attached the two resulting .config files.  Something in the diff 
between these is killing me.  Unfortunately, there are a *lot* of changes 
between them, which seems odd for a .config that's just minutes newer than 
the other one...

[Edit:  The .config files are not attached.  Too big for the mailing list. 
 I'm sure you can compare them without me attaching them.] 

Thoughts on what I should change from here?

Again, thank you very much for your help!  I look forward to any 
suggestions you might have.
