Subject: [PATCH] VIDEO: Newport Fix console crashes
Because of commit e84de0c61905030a0fe66b7210b6f1bb7c3e1eab [MIPS: GIO bus
support for SGI IP22/28] newport con is now taking over console from
dummy con, therefore it's necessary to resize the VC to the correct size
to avoid crashes and garbage on console
