Without knowing the internals of this hardward and without know the code of E,, I would start digging the ACPI stack
E is able to handle at least some ACPI events. I would wonder if there is a chance that E is sending some ACPI event that the bios recognises and power off the display. It could be a drivers issue when the kernel boots up. Try looking for the modules used, maybe start blacklisting and rebooting you may findout which one is the one givving truobles. Or maybe you could add a parameter to prevent this. Or even disable E's internal ACPI module There is also a cmd caled acpi_listen. You could create a script, add it to the inittab with logging to a file and then see if it's really an ACPI issue. In the other hand, if E it's playing with BIOS, then there should be a kernel module being accessed by enlightement binaries. Try looking for something with lsof. cheers!
