My Toshiba laptop (C650-16R, Intel i3, intel hd graphics) can now run longer, but I agree with all people saying this is a huge bug. On first run of Ubuntu I could enjoy the laptop almost 4 hours and a few days ago it only worked for more that one hour. Now I get almost 2 hours (better, but not perfect). I hope the battery is not permanently affected.
As cjcolella said, for people that switched to Ubuntu recently, just like me, the line in /etc/default/grub looks like this now (Natty, all updates):
GRUB_CMDLINE_ LINUX_DEFAULT= "quiet splash pcie_aspm=force"
