[olpc-help] SISUSBVGA - (re)compiling should not make a difference, should it?

[Andrew]

I did not compile the module and the kernel. I am on build 656, and I simply modprobe'd the binary (can't remember if i had to download them or not, at this point).  my sisusb_drv.so is in the directories below:

/usr/lib/xorg/modules/drivers/sisusb_drv.so
/versions/run/656/root/soft/sisusbvga/sisusb_drv.so
/versions/run/656/usr/lib/xorg/modules/drivers/sisusb_drv.so

It /seems/ to be properly installed (certainly, the module loads (automatically, on hotplugging!), without errors), and, as I wrote earlier, I am getting /some/ life in the external monitor -- just not a clone.

Yet, perhaps it's not fully functional precisely because I did not compile my own?  That seems improbable in my mind, but I may be wrong.

Can someone please help us get this to work?

thanks

andrew
