COMMAND_LINE_SIZE increasing in 2.6.11-rc1-bk6

[Janos Farkas <jf-ml-k1-1087813225@lk8rp.mail.xeon.eu.org>]

Hi Andi!

I had difficulties booting recent rc1-bkN kernels on at least two
Athlon machines (but somehow, on an *old* Pentium laptop booted with the
a very similar system just fine).

The kernel just hung very early, just after displaying "BIOS data check
successful" by lilo (22.6.1).  Ctrl-Alt-Del worked to reboot, but
nothing else was shown.

It is a similar experience to Chris Bruner's post here:

I also recall someone having similar problem with Opterons too, but
can't find just now..

rc1-bk6 didn't boot, and thus I started checking revisions:
rc1-bk3 did boot (as well as plain rc1)
rc1-bk4 didn't boot
rc1-bk7 booted *after* reverting the patch below:

> 4 days ak 1.2329.1.38 [PATCH] x86_64/i386: increase command line size
> Enlarge i386/x86-64 kernel command line to 2k
> This is useful when the kernel command line is used to pass other
> information to initrds or installers.
> On i386 it was duplicated for unknown reasons.

While arguably it's not a completely scientific approach (no plain bk7,
and no bk6 reverted was tested), I'm inclined to say this was my
problem...

Isn't this define a lilo dependence?
