rs/6000 e30 + 240 (doral) support.

Hello,

Here are 2 patches to make linux support the old IBM RS/6000 E30
(ppc604e) and 240 (doral). The support was written by Leigh Brown and
adapted from the patch present in the website:
http://home.tiscali.be/philipa/rs6000.html

These machines are old, but usable nowadays. Here in brazil we have
many universities with them, since they were distributed to some
projects between 1999-2001.

These patches are not invasive and easily portable to other kernel
versions... so I hope you all will try to support it.

PS: I'm not subscribed to the lists, so please CC me.
