[PATCH] ppc64: add MODALIAS= for vio bus

A non-broken udev would autoload also the drivers for devices on the
pseries vio bus, like ibmveth, ibmvscsic and hvsc.  This is similar to pci,
usb and ieee1394:

 /lib/modules/`uname -r`/modules.alias
alias vio:TvscsiSIBM,v-scsi* ibmvscsic
alias vio:TnetworkSIBM,l-lan* ibmveth
alias vio:Tserial-serverShvterm2* hvcs


 modprobe -v vio:TnetworkSIBM,l-lan
insmod /lib/modules/2.6.14-20051030_vio-ppc64/kernel/drivers/net/ibmveth.ko
