[LinuxBIOS] Intel SE440BX support

[Oscar Molin]

I have 2 Intel SE440BX and one Intel SE440bx-3 (it's some kind of subversion
to sebx-2)
These were very popular Intel OEM boards and were used by Dell, compaq,
fujitsu and the like.
If someone wants info on what chips they have etc I'm willing to be of
assistance and help with testing code one them to make them work.
Since they all have Intels soldered on flash chips you can't make too many
mistakes but I have no problem losing one in the process as I don't need all
of them.
