Sorry if this is a noob boob, but are there any patches
that will add FBIO_WAITFORVSYNC functionality to ioctl
I'm hoping to use the framebuffer in an embedded pc and
need as much mapped video ram as possible with the
ability to pan on a vsync. Would I be better off looking
at another manufacturer? It seemed that the Radeons give
a good Mb per buck ratio.
I got myself a 9250 128Mb PCI and so far found that I
can map all the memory to user space; but only after
I've started X on the device first and then closed it
down again. Otherwise I get "Found 0k...videoram" in
Any advice would be greatly appreciated?

Ville et al.
Many thanks for that, it looks promising; I'll have a
play around and see what gives.
Can anyone give me a clue as to how to get the radeonfb
module to recognise the video memory without first
starting x on the card. I'm assuming that something's
not been fully initiated so I'm having a hunt around
but no luck as yet. Are there any BIOS settings that
might be worth a tweak?
It's a CGA-9258PYVD (so an RV280) PCI card with 128Mb
that I'm trying to get working on a VIA Mini-itx board.

If this is not the primary card, you need to POST it.
