The T400 mute button issue when upgrading Ubuntu 9.04 64 bit

I just upgraded ubuntu to accept all the new libraries. It upgrades the kernel to 2.6.28-14 but on doing so, it rewrites "/boot/grub/menu.1st" so effectively overwrites the mute button fix. No worries. Just edit menu.1st again and put the acpi_osi="Linux" option back on the kernel lines!
