I tried all three combinations and all work with qemu:

1. (initrd-modules (append (list "cirrus" "cirrusfb")
2. (initrd-modules (append (list "cirrusfb")
3. (initrd-modules (append (list "cirrus")

I tried the version with "cirrus" on my VPS and it worked there too.

When I read the comments in the drivers, it looks like the "cirrus" is
implemented for qemu:

https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/cirrus/cirrus.c
https://github.com/torvalds/linux/blob/master/drivers/video/fbdev/cirrusfb.c

That's the result of my tests. I know too few about kernels/drivers to
really decide what the best would be here.

Ludo or Mark, could one of you go on further from here?

Thanks,

Björn
