How do you know that your lm(4) is at port 0x290?

From the list of the hardcoded ports from http://mdoc.su/n/lm.4,
searching the mailing lists for (wbsio0 -0x280 -0x290 -0x310 -0xa00)
reveals that lm(4) can also be present at 0xa10/8 (W83627DHG), 0xca0/8
(W83627DHG), 0xa30/8 (NCT6776F), 0xc00/8 (W83627HF) and who knows
where else.

The wbsio(4) driver basically acts as an auto-discovery mechanism for
these less common ports.
