Hi,
IMHO, the randconfig option make no sense sometimes. For me, My
computer need some must-have config options, like SATA and USB
keyboard config options. I think many other people maybe have similar
problems.
So, what about improve the randconfig? let's add some basic options ,
like oldconfig.

Hi,

so use boot_cpu_data instead of current_cpu_data.

As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse controller
on the PegasosPPC. This is because of a feature/bug in the OF device tree:
the "device_type" attribute is an empty string instead of "8042" as the
kernel expects. This patch (against 2.6.22.1) adds a secondary detection
