I got this working with the following workarounds that have been previously mentioned: 1. Hold down shift to bring up the grub menu at startup - add "nomodeset" to the kernel options. System boots up although the correct resolution is not detected, this is just temporary to make the following changes... 2. Add "setpci -s 00:02.0 F4.B=00" to /etc/rc.local 3. On reboot after step 2 the brightness was stuck at maximum, so I added "acpi_osi=Linux acpi_backlight=legacy" to the kernel parameters in /boot/grub/grub.cfg 4. On reboot, screen is the correct resolution and the brightness keys work (although the on-screen brightness bar no longer appears but I can live with that).
