[PATCH][v3] add consoles to v3 lbtable

[Patrick Georgi]

Hi,

when doing the patch for cbv2 to add console information, I promised to 
provide a compatible facility for v3, too.
Sorry it took so long, but here it is.

It currently uses the pci rom init config variable to decide if to add a 
vgatext console, because that's the best we have in v3.
Better ideas are welcome.

Regards,
Patrick Georgi
