argv[0] is garbage when the com32 module starts.

The computed cmdline is OK, before booting the kernel, but when the
kernel is booting and prints the commandline it got it only prints
garbage.

I can't check initrd prior to booting the kernel, but the kernel
complains that it isn't initramfs (it is) and then "VFS: can't mount
root".

Well, I based my code on linux.c. I used initramfs_load_archive in the
first versios, but as it didn't work I looked how it worked and used
that directly.

I don't link the command line parsing of linux.c. Mine works (well, it
prints the correct output), is smaller and IMHO cleaner.

But I'll try it tomorrow instead of mime. And just linux.c32, as it could
be unrelated to syslinux_boot_linux.

Do you think that borrowing 1K from the stack could cause problems?
