Re: Help port swsusp to ppc.

[Nigel Cunningham]

Hi.

I'd love to be able to help, but unfortunately the old assembly I know
is good old 6502 :> Hopefully someone else will pipe up and get you
going.

Once you do get it going, I'll be happy to help keep the other parts
updated, so far as I'm able.

Regards,

Nigel
