So from a quick look at smetana (sparc), wheezy 3.2.x kernel:
sunvnet has
alias:          vio:Tvnet-portS*
and sunvdc has
alias:          vio:Tvdc-portS*

Seems like the device tables have been there since a week or so after
adding the drivers (in 2007), so not really new.  Does udev know to load
that nowadays?

On partch (powerpc), squeeze 2.6.32 kernel:
hvc_console is not built
hvcs has alias:          vio:Tserial-serverShvterm2*
ibmveth has alias:          vio:TnetworkSIBM,l-lan*
ibmvscsic has alias:          vio:TvscsiSIBM,v-scsi*
iseries_veth is not present 

viodasd and viocd were removed in 2012
(ba7a4822b48fbc7afd6b567c18e316a03f46684d), and don't seem to be enabled
in the Debian kernels.

As to whether that's sufficient, your guess is as good as mine. 

Cheers,
Julien
