So i actually do use pmap_mapdev to get a handle to the table, but i dont
do that in smbios_attach, i do it in a function written to walk the table.

but, as i alluded to previously, the original author used
bus_alloc_resource() in smbios_attach() are you saying that i should use
pmap_mapdev() in smbios_attach *instead* of bus_alloc_resource()?

or am i missing the plot and there shouldnt even be an smbios_attach() ??

tnx!
