oddities that i forgot to mention.
without making any changes i did get X to start once. though a second attempt failed. randomly it will either return with the error upon startx or lock up so that the machine needs reset.
also i have:
and in /etc/rc.conf
in dmesg im seeing the nvidia0 lines come up, but after boot there arent any nvidia* in /dev
supermicro pdsba E6000/4000 core 2 duo,
2.4Ghz Intel E6600 @1066Mhz Corse 2 Duo chip
4gig ddr2 800 dual channel memory
#dmesg > dmesg.txt ; grep "irq 16" dmesg.txt
pcib1: <ACPI PCI-PCI bridge> irq 16 at device 1.0 on pci0
nvidia: <GeForce 7950 GT> port 0x4000-0x407f mem 0xd1000000-0xd1ffffff,0xc0000000-0xcfffffff,0xd0000000-0xd0ffffff irq 16 at device 0.0 on pci1
pcib2: <ACPI PCI-PCI bridge> irq 16 at device 28.0 on pci0
added: im starting to believe the issue is mainly an IRQ or PCI IRQ routing error. I can not move the card as it is the only PCI-E16x slot on the mobo. I have not been able to find a way to change the IRQ for the card either.
