I don't own an Eee, but having played with one, the key sequence

    Alt down
    Fn down
    SysRq down, up
    Fn up
    P down, up
    Alt up

should work just fine.  As long as you keep holding Alt, you don't
need to continue holding SysRq after the initial keypress.

SysRq over USB has never worked.  On PC hardware, Magic SysRq depends
on features of the built-in i8042 controller, which only handles PS/2
input.
