I2C external interrupt

All,

OK, I have successfully implemented an I2C I/F on my
Embedded Planet MPC823e platform (Linux kernel
2.2.14 HHL). Now what I'd like to do is interrupt the 823e
causing the PPC to initiate an I2C Write/Read transfer. I
notice that the I2C driver already installs its interrupt
handler using cpm_install_handler with an irq. Since a device
driver can not have more than 1 associated irq(?), has anyone
attempted to do something of this sort or have any
meaningful suggestions for me?
