I finally got tired of my rx2600 printing garbage at the end of
the list of ACPI tables so I decided to fix it.  Turns out the HP
rx2600 does not provide a DSDT in the FADT, so we were trying to
print a table at 0x0.  It does provide a X_DSDT.  This patch will
make acpi_get_table_header_early() prefer the X_DSDT over the DSDT
and adds more checking for null.  Looks like the same code is in
2.6 and 2.4, please apply for both.  Thanks,

	Alex
