OK, I will add this to grfabs_et.c.

I will add this here too.  This makes it quite simple to add to the Xserver,
as all the detection is already done.  Last night, I added the clock setting
at iobase+0x00 to the ET4000 initialisation.  640x480 and 800x600 modes were
OK [*], but I still can't get 1024x768 to work.  I shall try converting some
of the modes from VMG to XF86Config modelines and see if that is any better.

In the Xserver, inw and outw are defined as two byte read/writes.  Will this
always work on the TT?  Would it not be better to use the single word (16bit)
read/write (that is #ifdef 0)?  Or will that not work on the Hades?

Thanks,

J
