Opsss, I was too fast on the trigger; it didn't solve anything regarding acpi. No long ago we had a problem on the trunk with windows installation. It failed if the flag -no-acpi was not used. When I checked your patch the problem disappeared but when windows installation completed I discovered that it didn't use the acpi HAL. So I checked without the patch and got the same result too. Probably recent commits fixed the crash and from now the -no-acpi flag is not required during installation.
