Yes, at some point previously, I tried to explain I was referring to the 
physical tty console text mode. I'm sorry that wasn't more clear.

At one point I was able to use vga= to set the mode, but when that 
stopped working, I was looking for the new method.

I thought it was strange that the kernel command-line wasn't being 
modified during this whole discussion.

I've now tried video= and it works as expected.

Lol, I don't really care about how grub looks :-)

Thanks everyone for your efforts, and explanation about how the boot 
mode has changed with KMS. Learned a lot during the process.

Thanks,
Alex
