SubjectRe: FW: pIII Serial (or lack there-of)
Jones D ISaCS had the wisdom to write:

JDI> You shouldn't be able to read them either, as AFAIR, it's a ring 0
JDI> instruction. You should segfault immediately.

Yes, and then the kernel has the opportunity to "fake" (read: handle)
the instruction on you.

So the REALLY cool thing would be to have a proc-option that allows you
to SET your serial for the userspace apps..... (using this construct, it is
even possible to provide this without having an PIII)...

Greetings,
Arjan van de Ven
