not entirely sure what youre asking..
yes, I sent the same patch <cough> 2x.  Bad email day.

<aside>
Sometimes I wish I had one of those MS-idiot buttons;
"Did you attach that attachment yet"  Except it should work.
(ie read the msg, and find 'patch' or 'attachment' in context,
and ask only when its seen and nothings attached.)
</>

BTW, since HPA has been mostly disconnected lately,
I sent patch to Dave Jones, the other i386 boot Linux Kernel Maintainer.
He was ok with it, forwarded to Andrew Morton, who replied
(to Dave & me, but didnt add on hpa):

We had some nasty problem when we tried to do this on x86-64 recently.

It would be best to wait until hpa has had a think about it.


Curtis, since youre hacking at syslinux, could you try 3.08 proper,
rather than pre-10 or 11 ? (or is pre-10 same as released?)
It looks like your patch (or parts of it) are in 3.08 already.
But then theres that nasty -R in there ;-)

Once I patched len to 1024, my kernel sees the full commandline sent,
and acts accordingly.  Im using menu.c32. but no DISPLAY - the menu
gives me what I need, and I dont have to keep a display-file in sync 
with it.
