OK, I think I've seen it now. The API to acpi_add_table has changed too.
It's now passed the rsdp as the root of the table structs rather than rsdt.
Shouldn't we really have an announces list to advertise fairly fundamental API changes like this ?

Hi guys,
I've finally got my EPIA-N/CN400 port booting all of the way into linux (fc9 2.6.25)
I've been merging my latest back into a copy of the current trunk (R4506)to get patches together, but I've found that ACPI is now broken in my build.
It appear that the API to acpi_write_rsdp has changed to allow an xsdt table to be written.
I have tried including and xsdt and also setting the pointer NULL the results are both the same.
Is there some other table revision issue or perhaps alignment issue that needs to be taken care of ??
Thanks for any help. I'm on hols from tomorrow and would like to get the patch out before I go.
