Andy / Yuri,
To increase vmalloc I added a parameter to the boot line
in /boot/grub/menu.lst. I'm not near the box at the moment but I am
fairly sure I just added "vmalloc=256M" to the image boot line as
another option (along with "quiet" etc.)
I'll copy the actual boot file lines later.
It'll take me a while to digest and incorporate all this in to my
testing but I'll keep you both informed of progress.
