I noticed in the latest -mm patchset there is a new fb driver for nvida chipsets, I tried it out, it compiled fine with vesafb-tng enabled but wouldnt compile with out vesafb-tng which didnt make sense to me since that seems reduntant, but any way, why would any nvidia user wish to use nvidiafb since it prevents using the nvidia-kernel module and as a result, I am assuming there is no 3D support, i though I read somewhere that the nvidiafb driver mimics the xorg nv driver, whats up with this?

thats right, I found this via google www.kernel.org_cset
| Code: | # ChangeSet
# 2005/03/10 09:10:58-08:00 adaplas@hotpop.com
# [PATCH] nvidiafb: Add update framebuffer driver for nVidia chipsets
#
# Because nVidia keeps pumping out new graphics chipsets, it is becoming
# harder to add support for these with the old rivafb code. Currently, rivafb
# can properly support NV_ARCH_20 chipsets and older.
#
# Instead of rewriting rivafb to support the latest chipsets, I've decided to
# write a new driver, called nvidiafb. The aim is to closely follow Xorg
# development.
#
# Currently, this driver is based on the most recent CVS Xorg nv driver. Main
#
# - console acceleration for all chipsets
# - uses DMA instead of PIO
# - better LCD/digital output support
# - better monitor detection
# - support for Riva128 will be dropped as it cannot do DMA, rivafb
# will remain as the driver for this chipset
#
# It should work with Xorg/XFree86 nv driver, but as with rivafb, is not
# compatible with the proprietary nvidia driver.
#
# Once the code becomes stable, rivafb code will be trimmed to only support the
# Riva128 and perhaps some of the older chipsets. The code has been tested on
# several nVidia graphics card on x86 and x86_64. I'm still waiting for
# feedback from Guido Guenther regarding ppc.
#
# This need not go to mainline immediately, as I would prefer the code to
# receive rigorous testing in the mm tree.
