Re: [PATCH] PnP Fixes for 2.6.0-test9

# [PnPBIOS] read static resources on PnPBIOS init
# 
# The PnPBIOS specifications recommend that we read static (boot time)
# resources when the PnPBIOS driver is first initialized.  Because the
# PnPBIOS driver is not modular and can not be ran more than once per
# boot, it's safe to access the static resource data.  Many buggy
# BIOSes actually expect us to read from it first.  With this patch,
# the PnPBIOS driver will read static resources initially and then
# switch to dynamic mode when allocating resources for specific nodes.
