I've seen, that your patches were merged in master, however trying to
load the attached ldif (generated with patched oLschema2ldif with
X-NDS_CONTAINMENT mods) still waxes the schema. Looking at the modified
schema ldb it seems, that it still misses the oMObjectClass attributes.
BTW I've overcome the name collision by applying the following ldif:

dn: CN=DHCP-Class,CN=Schema,CN=Configuration,DC=kzsdabas,DC=hu
changetype: modify
replace: lDAPDisplayName
lDAPDisplayName: msdHCPClass

dn: CN=dhcp-Options,CN=Schema,CN=Configuration,DC=kzsdabas,DC=hu
changetype: modify
replace: lDAPDisplayName
lDAPDisplayName: msdhcpOptions

It probably makes MS DHCP Servers useless in the Domain, but I do not
intend to have any MS servers anyway.
