not found!

That is acpi reporting what it has done; no problem
When we get our product = fixed dsdt.dsl -- we are going to place it where initrd will find it & use "mkinitrd" so it will be added during boot like here:

from my nforce3-250Gb suse 9.3 fixed dsdt dmesg:
ACPI: Looking for DSDT in initramfs... found /DSDT.aml ... successfully read 19095 bytes from /DSDT.aml
ACPI: Using customized DSDT
ACPI-0293: *** Info: Table [DSDT] replaced by host OS



I'm still getting:
powernow-k8: BIOS error - no PSB
powernow: This module only works with AMD K7 CPUs
ACPI-0283: *** Warning: Error evaluating _PSS
even with fixed dsdt.
Obviously there's more work to be done. When I get the chance, I'll use "find & find next" in kwrite to see if this is in dsdt or another table -- such as ECDT.
Note: this may require a kernel work-around patch, more on this later.
Better yet, maybe a real guru will pitch in & help us solve this issue.

Got to go check my moma cows. I'll be back.
