The following source says that it dates back to at least 1996:

Chillax is a combination of chill and relax. Although top Internet search results say chillax originated with the 2003 film Final Destination 2, the word actually shows up on the Internet in personal ads going as far back as January 1996 and is included in a musician’s website that includes an Ebonics dictionary with a Google date stamp of February 2, 1996. Did anyone really think Hollywood could have created the word on their own?
Earliest Known Quotation (film, Final Destination 2, 2003, Spoken by an unnamed kid smoking at a gas pump.) “Chillax, biatch.” Earliest Known Quotation (print, The American Spectator, Volume 36, 2003): “He told me I was overreacting and to ‘chillax.’”
