So I take it it's more of a DHCP hack in which:
1- client boots and gets DHCP response from 10.215.144.7 with PXE syslinux info
2- client loads pxelinux.0 menu and selects menu that chains to Altiris PXE menu except, instead of calling pxechain.com or pxechn.c32 with the Altiris server's IP address, the client should "re-netboot" but this time, the DHCP server at 10.215.144.7 should not include any PXE information at all for this particular client/MAC, so Altiris can kick in.

I don't know how to do this but is this basically what you're suggesting?

Thanks,
