It can, it stores the extra stuff in the "ff:fe" part in TCAM, hence the
EUI-64 requirement. You should be able to make up any IPv6 address as
long as it contains ff:fe in the right place. I've been using 3750's for
a couple years now with IPv6 access lists and I've just come across this
annoyance while migrating things out of 2620:0:950::/48 and over to
2607:fe70::/32.
