The following comment calls however for some caution when it comes to hoping that a direct port to an ACPI-based system will work: * only supports the mobile chips in D2 mode, that is typically what * is used on Apple laptops, If I'm guessing correctly, D2 is "clocks off, static registers preserved" while ACPI/S3 certainly means D3 (power off) -> even more device state to be restored. > I don't have time to look at this right now, but will do so as soon as > another lazy weekend comes up. If you haven't already done so, you might want get access to the ATI docs *before* your lazy weekend... > If someone else has the time and inclination (Ole Rohne? ;), please > go ahead! I've resolved not to waste more time on it - at least for the moment. And I'm quite happy with the POST-hack - dirty as it might be... Ole PS: I've updated the patches at to linux-2.5.64-bk11 and XFree86-4.3.0. I hope they're OK this time... ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
