nobody cared for tg3 w/ 2.6.17-rt8

[Robert Crocombe]

2.6.17-rt8

irq 106: nobody cared (try booting with the "irqpoll" option)

Call Trace:
      <ffffffff8029d0f5>{__report_bad_irq+48}
      <ffffffff8029d307>{note_interrupt+453}

handlers:
[<ffffffff880036f0>] (tg3_interrupt_tagged+0x0/0x91 [tg3])

but as noted in the boot message, irqpoll isn't support for -rt.  I
haven't seen this problem when running vanilla 2.6.17.  Just after
that:
