We already have a patch doing exactly this in -mm: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21-rc3/2.6.21-rc3-mm2/broken-out/jdelvare-i2c-i2c-nforce2-add-mcp61-mcp65-support.patch > 00:01.1 SMBus: nVidia Corporation MCP61 SMBus (rev a2) > Subsystem: Elitegroup Computer Systems Unknown device 2601 > Flags: 66MHz, fast devsel, IRQ 10 > I/O ports at fc00 [size=64] > I/O ports at 1c00 [size=64] > I/O ports at f400 [size=64] > Capabilities: [44] Power Management version 2 BTW, note how the MCP61 has not 2 but 3 64-byte I/O areas declared. The previous chips used BAR 4 and 5, this new one additionally uses BAR 0. Without documentation it's hard to be sure this is a 3rd SMBus channel, but it sure looks so. Maybe you'll want to hack the i2c-nforce2 driver a bit to confirm or infirm this theory. -- Jean Delvare - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
