Does anyone have processing times for Tri-X when it is pushed to 800/1600 ISO.? I'd like to use D-76 or Microdol-X because it is readly available to me.

Has a bunch of info on Kodak films. They suggest adding 60% to developing times for a two stop push of Tri-X in D-76. They also listed something for Microdol-X which surprised me since that's usually a developer that results in some loss of film speed.

DADA or push process is done with 400 speed film with ASA set at 1600 then it is developed with 300 ml Polymax and 300 ml water for 9 min at 68 degrees f. 9 min constant agitation. Fix as usual of for longer and permawash normally. I have had excelent results with this process and it is inhanced by using fiberpaper(matte) in which you can color on with color pencils.

Microdol-X, when diluted 1:3, does not reduce film speed. It is slow working at this dilution so you should process at 75 deg. F unless you're very patient. Start with 17 min. for EI 800.

Tri-X @800, 1600, etc.

Have you consideed other developers for your needs? D-76 tends to block highlights with increased development times. Microdol-X is a 'fine grain' (read that 'low accutance') developer and is not intended for 'push' processing. I've recently had very good results with Kodak's new XTOL. It should be just as easy to find as any other Kodak developer. I've used T-Max developer for pushing for years with great results.
