Hi, I am typing this message on a W520 running 9.0 stable, which should be similar enough to the T520. - MBR boot works fine, but GPT seems to be impossible (Lenovo appears to have messed up again). - The NVidia driver is working almost perfectly once you enforce it in BIOS, but occasionally (3 times in last 2.5 months) the screen starts displaying a strange block pattern after some time and renders the display unusable until I restart X (logging in via SSH works, as does the power button == ACPI shutdown). Haven't been able track the cause down yet. - Suspend seems to be unreliable, so I stopped trying (back on BETA2). - acpi_ibm.ko works once you patch sys/dev/acpi_support/acpi_ibm.c, line 338, and replace "IBM0068" with "LEN0068", which makes most of the multimedia keys usable. - Wireless is working (iwn), but I'm not using it that frequently so YMMV. - I cannot comment on bluetooth, camera or SD card reader, since I never use those. But there is one annoying problem I did not manage to fix yet: The screen brightness control does not work at all, i.e. it's always at maximum (hw.acpi.video sysctls seem to have no effect). All in all, this laptop is a nice desktop replacement, just don't expect the battery to last too long. Best regards
