VESA resolution in VirtualBox (amd64)

[Daniel Koch <news%danielkoch.com.br@localhost>]

Hi,

Where is the vesa command in boot menu? How can I enable this?

I'm using NetBSD 5.1 amd64 as guest OS in VirtualBox (4.1.6). Even 
compiling the kernel to use genfb I can't extend the console size.

I don't want to switch to i386 in order to use KVM/vesa driver.

Regards,
DK
