ACPI is enabled. APM is disabled.

Epia LT BIOS is at 1.01 presumably. BIOS update to 1.03 fails as
vf-1.02.exe, presumably due to freedos, does not recognise the VIA board
and complains about it.

Also due to board swap last year it can be the case that HPET has so far
not worked at all on EPIA LT.

The board has VIA C7 CPU and VIA CX700M2 Unified Digital Media IGP
chipset which supports HPET.

Can it be that the kernel lacks support for CX700 hpet?
Or is it a matter of getting the BIOS upgrade to work?

Your current BIOS doesn't provide an HPET ACPI table, which is the way it's supposed to indicate support. The kernel only supports force-enabling HPET on VIA for VT8235 and VT8237.
