This part (now named linux16) is kept for backward compatibility only. And it looks like current implementation of linux command doesn't suffer this limitation. Can you confirm?
BTW I'm at ETH too

Hello!

I just noticed, that the pc linux loader (loader/i386/pc/linux.c) always
truncates the kernel command line to less than 256 characters.
Well since I needed a longer command line, I fixed this problem.
Hi,

Thanks for your effort, but note that this can't be changed carelessly.  It's
possible we have this limit for backward compatibility.

If newer versions of Linux allow a longer cmdline, our code should check for
that instead.

If you look at the patch I send on Feb 11, I think it does all the necessary 
checks.

Also, would be cool if you can check whether loader/i386/linux.c also has
this problem.

Well, it uses a fixed 4k command-line area. But I don't know, if this is a
problem there.

Greets,

Jan
