people with intel 82443BX chipset

[hshoexer_(_at_)_openbsd_(_dot_)_org]

Hi,

everybody with an intel 82443BX chipset on her mainboard, please try this
diff.

Background:
the data sheet of the intel 82443BX host bridge says bits 1:0 of the
configuration address register are reserved, ie. addresses have to be 32bit
aligned.  So, 0x76 is truncated to 0x74.

The diff below should fix this.

Report success to me, regression to tech_(_at_)__(_dot_)_

Thanks!
