"VIA686a test code..." in arch/i386/kernel/time.c (introduced in
2.2.19pre1?) produces surprising results[1] on my AcerNote-950 (which
doesn't have a VIA686 (it's a Pentium) and FWIW does have BIOS horked in
at least the APM department). Searching The Fine Web for "probable
hardware bug: clock timer configuration lost" suggests that this "fix"
may be causing "surprises" on other non-VIA686a machines too[2].

Attached (COMPLETELY UNTESTED) patch attempts to implement a kernel
command-line switch "via686_hacks=none" to disable this "feature". The
framework for this patch was lifted from arch/i386/kernel/apm.c .

Am I barking up the right tree here?

Is it worth my while trying to beat this one up in the next 24hours (if
not I'll put it in the fridge till I'm on Jury Duty next week :-( ).
