Error installing nvidia driver on x86_64 using dkms ("bad exit 10")

Hi,

I just replaced my old, trusty A7N8x-E Deluxe mobo by a new, shiny
Intel DG33BU. Installing Fedora 7 on it was ok and fast (~20min), but
there was no network. I downloaded latest kernel from another computer
and was able to bring up network. Along with the new kernel I manually
downloaded and installed:

dkms-2.0.16-1.fc7.noarch.rpm
nvidia-x11-drv-100.14.11-1.fc7.x86_64.rpm
nvidia-x11-drv-32bit-100.14.11-1.fc7.x86_64.rpm

(BTW: do I really need the drv32 RPM? What for?)

I upgraded the kernel to latest version:

kernel-2.6.22.1-41.fc7.x86_64.rpm

When I rebooted the first time, nvidia driver build failed saying I
didn't have kernel sources. I then realized I haven't installed
kernel-devel.  Downloaded it, installed it, rebooted. No joy. I then
realized kernel-headers hasn't been upgraded (please cut me some
slack, it was almost midnight ;-)). Upgraded it, rebooted, still no
joy.

What happens is that dkms start installing nvidia driver, but fails
after a short while with "bad exit status 10". It's not a problem with
dkms, because dkms-ntfs-2.1.28-2.noarch.rpm is installed and working
fine.

I am not at home right now, so I will not be able to give further
details until I come back home in a couple of hours, but hopefully the
info above will allow someone to help me with this issue...

I didn't know where to look for logs (neither /var/log/messages nor
dmesg shows me anything about this failure), but I just found this
thread which might be helpful:

Still, I'd really appreciate any help.

TIA
