I have fixed the "stock" DSDT for my Dell Inspiron 5000 (Model: PPM). It compiles fine using iasl from the acpicatools port, and enabling ACPI no longer causes the LCD to blank on startup.
Additionally, I have written a patch for version 1.29 of the sys/dev/acpica/acpi_ec.c. The patch affects the EcWaitEventIntr function to better parallel the functionality of the EcWaitEvent function. In summary, the changes are: 1) Added a call to AcpiOsStall to wait one microsecond before reading the embedded control status for the first time (this is done in EcWaitEvent). 2) Re-wrote the remainder of the function to use a single call to ACPI_MSLEEP that will wait up to 10 ms (again, from EcWaitEvent) for the embedded control status to be updated. I wrote this patch to reduce the frequency of "ACPI-0432: *** Error: Handler for [EmbeddedControl] returned AE_ERROR" errors. The code was written in a way to call tsleep 10 times and wait for only 1 tick each time. This resulted in a wait that was too short on my machine. The patch has cleared up most of the errors by increasing the wait time.
