These are probably all declared in a SSDT.

iasl error... somewhat ugly, I reask whether these nameclashes can be
fixed somewhat more generic than adding fixed string tokens to device
method declarations in yacc.
Renaming all DMA to e.g. _DMA_ (beside the ones where the DMA keyword
should be used, not sure if there is case in your DSDT) should work
around that.

Don't know, follow up error from above?

Better get the latest acpica-unix from:
http://developer.intel.com/technology/iapc/acpi/downloads.htm

Use acpidump, do not cp /proc/acpi/dsdt (this one is going to vanish
sooner or later).
Then use the compiled acpixtract from acpica-unix (not the perl one from
pmtools, that one gets obsolete). You now should get several tables
DSDT.dat SSDT1.dat SSDT2.dat ...

If you cut of the header (and closing '}' at the end of the table) of
the SSDTs and C&P them to the end of the DSDT (inside the last closing
'}') everything should compile fine.

The latest iasl compiler should add External statements at the beginning
of the disassembled table, but this does not work perfectly yet.
You can:
iasl -e TABLE_WITH_EXTERNAL_DECLARATIONS.aml -d TABLE_TO_DISASSEMBLE.aml
to let iasl resolve External symbols correctly.
But this is also not fully (not at all..) implemented.

I am currently playing with that, can you send me your acpidump output,
please.

Thanks,
