Latitude D630 storage driver problems

Body

The Latitude D630 has been going Blue Screen after initial install of the base Vista Enterprise OS.  The BSOD flashed by so quickly that we cannot see it.  After some poking, we were able to determine that this is a 0x0000007B STOP error, caused by non-availability of a compatible storage driver.  If we force the on-board Intel "Matrix" storage chip into "ATA" mode from "AHCI", we are able to boot the system.
 
A working install deployed from the Dell Vista Business OEM OS media has the following drivers running, all using Microsoft-branded drivers:
 
Intel(R) ICH8M Ultra ATA Storage Controllers - 2850 : intelide.sys
Standard AHCI 1.0 Serial ATA Controller : atapi.sys, ataport.sys, msahci.sys, pciidex.sys
 
Interestingly, msahci.sys is also present on out Vista Enterprise media.  What is the deal!!???
 
After running the Intel Turbo Memory A00 driver "setup.exe" that we downloaded from Dell, the Standard AHCI driver gets upgraded:
Intel(R) 82801HEM/HBM SATA AHCI Controller : iaStor.sys
This driver works without causing a blue-screen error.
