Problem with s5000PAL ACPI seems to be the problem

I have further diagnosed the problem with the S5000PAL.

When I boot up with ACPI enabled it is terrible (regular / default mode).

It freezes at many different spots. If it is able to get to the 
/trying to start_init: trying /sbin//init then it takes about 20 
minutes to do whatever it is doing and then boots up. During ths time 
nothing is loogged on the screen with debug mode enabled.

If  it does not get to this point randomly it gets completely stuck. 
It freezes at 2 different points in the ACPI init section and does 
nothing. It seems ot be like rolling the dice on a reboot :)

If I boot up with ACPI disabled (option #2) it boots completely fine 
with no visual problems.

What is the implications of not running it under the ACPI mode?

Any ideas on how to get it working with this mode?

Am I the only person with this problem on this motherboard?

Thanks for any assistance,
