Hi,

I can report that the kernel patch for enabling DSDT for 2.6.28 patches a
2.6.29 kernel OK (Fedora 11).

I've followed the various instructions (with corrections, because none of the
seem to be exactly right - out of date?) and have patched a DSDT and got it to
load from the initrd:

# dmesg | fgrep -i dsdt
ACPI: DSDT BFDE4000, BACC (r1 HPQOEM SLIC-MPC        1 MSFT  1000013)
ACPI: Checking initramfs for custom DSDT
ACPI: Found DSDT in DSDT.aml.
ACPI: Override [DSDT-SLIC-MPC], this is unsafe: tainting kernel
ACPI: Table DSDT replaced by host OS
ACPI: DSDT 00000000, BAC7 (r1 HPQOEM SLIC-MPC        1 INTL 20090123)
ACPI: DSDT override uses original SSDTs unless "acpi_no_auto_ssdt"
ACPI: EC: Look up EC in DSDT

The problem is that it seems to be completed ignored!

The acpidump output with and without the custom DSDT is identical!

The problem I'm trying to solve is this one:
