Add a small hack to UserConfig that allows to override the number of
EISA slots to probe. This is mainly intended to allow installing the system on an HP Netserver with an on-board AIC7xxx EISA SCSI controller, that is sitting on EISA slot # 11. Documentation updates explaining this hack will follow shortly. Note that this can go away again as soon as the EISA device probing is more intelligent about the address space clash with the PCI address space. 2.2 candidate. Not objected by: freebsd-core :)
