Try adding this at the end of your kernel line options in GRUB:

video=1600x1200

If you are lucky your video card driver will cooperate.[1]  If not you may 
need to either add the refresh frequency, e.g. video=1600x1200@60Hz, or if 
your video drivers won't cooperate you'll have to add 'nomodeset' to disable 
KMS and specify your vga resolution of choice.

I tried this on with radeon card and it works.

I used to use old grub, of course, and used this on the kernel line:

(from 2010)

  title 2.6.32-r1
  root (hd0,0)
  kernel /vmlinuz  root=/dev/hda5 vga=0x31b video=vesfb:mtrr:3,ywrap

 Don't know dupe about Ubuntu...

My goal is a nice big fat high resolution console mode.
Something on the order of 1600x1200

Didn't dig into kernel docs just now... but long long ago using old
grub I dug up the chart Mick mentions .. It might have changed by now
but probably not.

I kept it in comments on /boot/grub.conf down thru many installs
and several different OS's.  Here is one from 2010 gentoo (On the same
grub.conf as the title, root and kernel line above)

## 640x480 800x600 1024x768 1280x1024
##   256 0x301   0x303   0x3050x307
##   32k 0x310   0x313   0x3160x319
##   64k 0x311   0x314   0x3170x31A
##   16M 0x312   0x315   0x3180x31B

So, I can probably figure out where to put stuff like that using Grub2
but what I wanted to know about is using the Kernel modes KVM alone.

Hence the subject line about what to set `in kernel'.

Guess I should have specified using KVM and made it a bit clearer.
Since there are kernel settings related to using the stuff above too.

I may need to post again with a better subject line.
