Yes, it's weird, but if you use the ubuntu's grub, that will be in line 
with what I expect because that's what I use. My version number is now 
at 1.98+20100804-5ubuntu3, but I had used 1.96 (I think) onwards and 
updated my dedicated grub partition continually to the latest and check 
the difference. Other than the minor changes in format which doesn't 
make a diff, like " " and ' ', ( ), (hd0,7) and '(hd0,msdos7)', the main 
diff is in the commands, like --overlay, --output, mkrescue etc.

Another odd thing, my previous message reports that I booted fine with 
"root=LABEL=xxxxx" while you could not. I did not mention, because I 
don't want to further confuse you, is that you booted fine without it 
*and* when I tried it without the line, it goes into the (initrams) busy 
box. Weird huh? I thought that since you booted okay now, after all the 
effort, I wouldn't want to burden you with more confusion.

So I rechecked the use of your label name, seems okay - less than 16 
characters, underscore okay, etc. So it's really strange. I know I've 
edited out a lot of 'parameters' in my dedicated grub, like recordfail, 
savedfault, load_video, grubenv, gfxterm, gettext, but these shouln't 
make the difference in the problem we talked about. And I've confirmed 
with using the unedited (original) grub too to verify (configfile to the 
OS grub).

But if it now works for you, guess that's what matters most.
And, if you find out what's causing the weirdness, let us know.

So take care and regards - Goh Lip
