[Nouveau] nouveau framebuffer sync polarity

[schmidtler at t-online.de]

Hello everyone,
i use the noveau framebuffer device in kernel version 2.6.37.6.
my graphic adapter is a msi 9500gt, connected to a Barco CRT projector.
The Barco will only accept RGB signals with a negative sync.
Is there a kernel command line parameter to force negative sync
polarity?
Or is there a user space command to set framebuffer parameters, fbset
does'nt work with nouveau frame buffers.
