[Grml] grml virtualbox

I finally got it to work but I am not entirely sure how. I think the 
only change I made between tests was to increase the ram from 1024M to 
2048M and the vram from 128M to 256M. I tried moving just the ram back 
down to 1024M and got the same problem with it hanging during the boot. 
Version grml32-full-2014.11 doesn't require more than a gig of ram, does 
it? It could be some kind of weirdness with it being a virtual machine. 
If I have time, I will repeat the test. Bump it back up to 2048 and see 
if it hangs. If not, take it back down to 1024 and try it again.

I'm still working on that goal of creating a grml iso with a kernel 
patched to support hardware speech synthesizers. I don't know if I want 
to mess around with the boot issue too much. I've got a working vm and I 
might just move on to trying to get the grml kernel recompiled.


As I write this, it occurs to me that I have an old PC with 512M of ram 
and a bootable grml32-full-14-11 thumb drive. I can probably just try it 
on that. It'd take me 5 minutes maybe.
