I've been using for the last month a custom method for switch the cards, which involved having two DSDT, one for each card. Although this method worked to keep the currently active card on, I still needed to boot XP if I wanted to switch.
But now, as I did a clean install,, I decided to try the "new" method everyone is using, which is that sony-laptop moule by Eva. I though it was draining my battery really fast, even with the Intel on. As I wasn't using this module before and my battery wasn't draining so fast, I decided to remove it. Okay, now the weird part. Without the module it still works! I believe it has to do with the acpi_osi="!Windows 2006" used in Grub. I tried something along this line before (when messing around with the DSDT) but never worked, because it was in the wrong place! So, I believe this is good news. Or at least they are for me, because I wasn't really that interested in the sony-laptop mode. Still not sure how battery life goes, as it's still charging :)
