Interesting, my laptop is also a FS. Im runing the same gutsy too and its the other way round, blitzmax on ubuntu is fastest for both 3d and 2d stuff. Are you sure you have direct rendering? Make sure you have no xserver-xgl installed.
Also, if your FS lappy is ATI like mine, use the latest ati proprietry "fglrx" driver, not the "ati" one. Seek out a program called "Envy" it sorted my driver stuff right out.
