Thanks, I will do that tomorrow, In the mean time I'll add some simple
research I did so far for the benefit of the log.

* Upstream explicitly says that the R500 transreflective display is
supported, as is AMD64, so the machine should be supported I guess.

* The program is bailing out in kernelinterface.c, it first checks if it
can access TOSH_PROC, which I can't see where it is set, but is set to
/proc/toshiba; neither this nor /dev/toshiba exist on the machine.

void
detAccessMode()
{
 accessMode=ACCESS_DIRECT;
 if ( 0==access(TOSH_PROC, R_OK) )
   accessMode=ACCESS_KERNEL;
 else if ( 0==access("/proc/acpi",R_OK) ) {
   fprintf(stderr,"required kernel toshiba support not enabled.\n");
   exit(1);
 }
} /* detAccessMode */

* so then it bails since we can access /proc/acpi since toshiba_acpi is
loaded we have /proc/acpi/toshiba/.

* if I force a return of ACCESS_DIRECT I get "toshset: unable to get
BIOS version"

* if I force a return of ACCESS_KERNEL I get "toshset: unable to get
machine identification"

This bug seems to be known to Ubuntu.
