    Default: Disabled and Accepted.  It is very similar to standard
    CHAP (type 0x05) except that it issues challenges of a fixed 16
    bytes in length and uses a combination of MD4, SHA-1 and DES to
    encrypt the challenge rather than using the standard MD5 mecha-

So I would guess that it is supported.  All you would have to do is add
"enable mschapv2" to your ppp.conf file.
