BugLink: https://launchpad.net/bugs/583983 Symptom: on a significant number of hardware, booting from a live cd results in capture working correctly, but once the distribution is installed, booting from the install results in capture not working. Test case: boot from Ubuntu 10.04 LTS live cd; capture works correctly. Install to HD and reboot; capture does not work. Reproduced with 2.6.32 mainline build (vanilla kernel.org compile). Resolution: add SSID for Acer Aspire 5110 to the position_fix quirk table, explicitly specifying the LPIB method. I'll be sending additional patches for these SSIDs as bug reports are confirmed.
