This is not that kind of simple for your tablet pc. IIRC apanel does not 
support all the keys on FSC tablet PCs (tested as last with FSC T3010, P1510 
and a ST502x) and the problem is you need to poll the SMBios all the time.

No, they should not, because this buttons emit no keyevents and are also not a 
acpi key.

I'm not sure if it make sense to invest time here. IIRC FSC is already 
developing a own new driver specially for the panel and tablet PCs, but I'm 
not sure about the state of development and how they plan to 
release/distribute the driver, but I try to find out.
