[PATCH] Ash execution and VTs

["Claudio Matsuoka" <cmatsuoka@gmail.com>]

Hi,

I'm commiting these to the CVS repository. Previous code had the
strange effect of starting the console at the second VT and not
executing the shell. The first problem was caused because ELKS wants
tty1 to be minor 0 and not minor 1 like Linux, and the other because
the Minix file loader was not able to load files with total size
(minus 32 byte header) larger than a 16-bit integer -- I wonder how it
worked in older versions.

Here are the patches:
