I have a rivafb module, which loads fine and produces no output on
stderr or syslog. What does "gain control of the nvidia i2c busses"
mean? That sensors-detect should find them? It doesn't for me:

modprobe -v rivafb
sensors-detect
...
Driver `eeprom' (should be inserted):
  Detects correctly:
  * Bus `SMBus nForce2 adapter at 1c00'
    Busdriver `i2c-nforce2', I2C address 0x50
    Chip `SPD EEPROM' (confidence: 8)
  * Bus `SMBus nForce2 adapter at 1c00'
    Busdriver `i2c-nforce2', I2C address 0x51
    Chip `SPD EEPROM' (confidence: 8)
Driver `it87' (should be inserted):
  Detects correctly:
  * ISA bus address 0x0290 (Busdriver `i2c-isa')
    Chip `ITE 8712F Super IO Sensors' (confidence: 9)
...

Same output as always.

Are we talking about the same thing?

Linux .. 2.6.13-15.7-default #1 Tue Nov 29 14:32:29 UTC 2005 x86_64

Where? The kernel config doesn't seem to know about it:
zgrep -i ddc /proc/config.gz
gives no output. Grepping through the kernel source doesn't tell me
anything more, and none of the 5 rivafb module paramters have to do with
DDC.

Thanks,

Volker
