Stock == 'Vendor patched' (In this case 2.4.18-6mdksmp)
Recompiled == 2.4.18 (grabbed from kernel.org, no patches)

I have no idea.  How can this be determined and set?

stock==see above.
Doing a diff on the .config and .config.old for the kernel compile
(which cut back the number of APIC errors and the lost interrupts):

< # CONFIG_MICROCODE is not set
< # CONFIG_X86_MSR is not set
< # CONFIG_X86_CPUID is not set
---
> CONFIG_MICROCODE=y
> CONFIG_X86_MSR=y
> CONFIG_X86_CPUID=y

< # CONFIG_PM is not set
< # CONFIG_ACPI is not set
< # CONFIG_APM is not set

<snipped a bunch of power management options>

As a further note, this machine is does not receive (nor will it ever
receive) heavy traffic.  The machine just needs to be UP and able to see
hard drives on the dang Promise RAID controller (which was the whole
reason that I had to tinker with the kernel in the first place).  If I
need to shut off the SMP ability of the MB, that is an option since I
think a single processor will handle the traffic fine (1 Ghz is probably
overkill).

The second net interface on the board is un-used.  (Mostly this is a
reply to Nick's response about ping floods.  I may go with the
resolution of -noapic in lilo.)

Thanks, feeling stupid(er),
