Bouke released a new version of his RemoveHBA.sh script. The new version is also compatible with ESX 3.5 update 4:
This new removehba script removes the HBA drivers from the ESX 3.x ISO. Added support for 3.5 U1, U2, U3 & U4. VMware changed some files where the drivers were in and the script is taking care of that now also.
