You either need to execute the video BIOS to initialize the hardware registers, or initialize the hardware registers themselves.That is what the user mode reset program does. The problem is, how do I get it to run before calling the device's probe function? Most of the framebuffer drivers assume that the hardware has already been reset in their probe code.<shrug> You do precisely what you just said: run it before the device's probe function. That typically means either initramfs addition or using 'install <module> command...' in /etc/modprobe.conf.
How does install module work if one driver is servicing several adapters? What if one adapater is in the card at boot and another shows up via hotplug?
