Description of Problem:

In recent attempt to install on a machine with 14 spindles we found
out that buttons for picking up drives to work on them with fdisk
do not fit anymore on anaconda screen and there is no way to scroll
that long column.  Yes, I do know how to work around that trouble
but others may have a head scratcher.

The simplest way to provide for more buttons seems to be to put
them in parallel columns when the current column is getting too long.
This should provide for quite a number of drives as around dozen
seems to fit yet in the current arrangement.  Scrolled list probably
would provide more of a breathing space.
