PCI bridge optimization will be moved to pciutils soon.

But if you want to find out which set of options is best for
your setup, it takes a lot of time to recompile the kernel as
many times.

I vote for making it an option settable on the kernel command line.

So, what Cyrix-related things do we need to have in the kernel?

- Suspend on halt: Do we really need to set it up during kernel
boot? The example posted earlier mentioning system which died of overheating
before it reached the rc scripts doesn't seem to be important from my
point of view as it's certainly a HW problem and a machine suffering from
such problems won't go reliably anyhow.

- NO_LOCK (Coma bug workaround): Does anyone have a working solution
(Alan mentioned the original one broke some X servers)?

- VSPM: Probably not worth supporting as the performance gain is
almost unnoticeable.

The rest of Cyrix features seems to be solved cleanly by userland utilities.

Have a nice fortnight
