To be honest, I didn't know the 82801 SMBus controller supported memory access. Does it actually work since the first supported controller (82801AA)? But anyway, I can't see how using it solves any problem. I guess you access the very same registers, just using a different method. If the BIOS is actually using the SMBus controller, you have exactly the same conflict as before, the only difference is that it is no longer reported. This would be a regression, not an improvement. -- Jean Delvare SUSE L3 Support -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
