You are right, style() should return a derived class of QStyle
with a redefined drawPushButton().

Grepping through all *.sip files shows that drawPushButton has
been redefined.

Finally, I decided to add

print self.style().__class__.__name__
(self.style().className() is in the process of being fixed,
it should work in the CVS version, I believe) 

I was expecting QMotifStyle() (running Linux)

Surprise: it was the generic QStyle().
So, I added a statement
app.setStyle(QPlatinumStyle())
in main()

That works!

Here, your revised code:
--
#!/usr/bin/env python

import sys
from qt import *

class MyPushButton(QPushButton):
    """"""
    def __init__(self, parent=None, name=None):
        QPushButton.__init__(self, parent, name)
        print self.style().__class__.__name__
   
    def drawButton(self, painter):
        self.style().drawPushButton(self, painter) #!error
        self.drawButtonLabel(painter)


def main ():
    """main"""
    app = QApplication(sys.argv)
    app.setStyle(QPlatinumStyle())
    mybtn = MyPushButton()
    mybtn.setText("test")
    app.setMainWidget(mybtn)
    mybtn.show()
    app.exec_loop()

if __name__ == '__main__':
    main()
