+Subject: [PATCH] x86_64: Don't sanity check Type 1 PCI bus access on newer systems
+
+Horus systems don't have anything on bus 0 which makes
+the Type 1 sanity checks fail. Use the DMI BIOS year to
+check for newer systems and always assume Type 1 works on them.
+I used 2001 as an pretty arbitary cutoff year.
