Really cool to see that little Penguin! It's exciting! (This is the
MAXine with on-board frame buffer)

A PMAGB-BA mounted in the MAXine with a kernel that only supports the
onboard frame buffer doesn't work. A kernel with only PMAGB-BA support
displays until `This is a ...' and the machines runs fine besides
that. Maybe changing the base address? I'll try that anyway.

Meanwhile it's available at
alert: it is against linux-2.2.1-dec.tar.gz not the CVS source.

Another remark: normal init with these kernels.

Great work guys! I like the console font, it is beautiful on a 17".
