Vesa again: Switch mode in pmode ?

Hi !

I know it's not really an original question, but I don't have v86 tasks, and I wish to switch video mode... My kernel is already started, so I have to do it without BIOS calls.
I've read posts about Vesa 32 BIOS extension, and I've read the docs, but what is the state of the art ? Does it work ? Have you any pointer to a working implementation ?

Thanks !

VBE 3 works fine, but only with graphic cards that support it,
but you can use VBE2.x function without having v86 tasks working, u have to switch back to real mod switch to VESA mode and switch back again to pmode...

... or use a VirtualMonitor to do the switch...
