Or if we should just do this in linuxbios, and use the linuxbios i2c code?
That makes sense -- it's only a single register write to enable the
DCON.
However, we also want the framebuffer device in the Linux kernel to know
that it's there, so that it can pick the special [EMAIL PROTECTED] mode
instead of a normal CRT mode. Can we just indicate its existence in the
OpenFirmware device tree? Oh, wait.... :)
I2C + NAND in the kernel will add ~60k, FYI.
But I just had a thought - Why not probe the DCON in LinuxBIOS (using the
existing smbus code), and set a byte somewhere in the PCI config space if
it exists? That way, we could communicate the existance of the DCON to the
kernel without going out of our way to do anything stupid with virtual
registers.

we can do that. But it's our kernel and bios -- can't we just put some
info at page zero (or mod the command line) and leave it at that?
