I believe these final issues have already been fixed:

---
http://marc.theaimsgroup.com/?l=linux-scsi&m=115226175822438&w=2

From: Erich Chen <erich@...ca.com.tw>

  1- fix sysfs has more than one value per file
  2- PAE issues (cast of dma_addr_t to unsigned long)
  3- unblock SYNCHRONIZE_CACHE

And another one after that that Andrew brought up:

http://marc.theaimsgroup.com/?l=linux-scsi&m=115259088411283&w=2

I see that all of this was in 2.6.18-rc1-mm2

 SCSI fixes.

-drivers-scsi-arcmsr-cleanups.patch
-areca-raid-linux-scsi-driver-update7.patch
-areca-raid-linux-scsi-driver-update7-fix.patch

 Folded into areca-raid-linux-scsi-driver.patch

+areca-sysfs-fix.patch

 Fix breakage due to sysfs API changes.

But I don't see anything in 2.6.18-rc2-mm1 or 2.6.18-rc2
