CS8900a problems (very long post)

Currently, I am trying to interface the a cs8900a to the motorola 6812 microcontroller. A desecription and schematic of the board I am using can be found at

Additionally, I have been using the cs8900a in 8 bit mode (or trying to). I am able to read from registers or any place in internal memory using the packetpage pointer and packetpage data registers (i.e. I can read the product ID register). My main problem is that I I am unable to transmit any packets. I am connecting my ethernet module to my pc via a crossover cable. On my pc, I have an ethereal packet sniffer running to see if I was able to send anything. Right now I am able to get a bid for transmit (the RDY4txNow bit goes high) but it will not transmit anything. Also when I put the while loop in for the repeated transmit, the cs8900a will not reset and the link light will not come on. If I comment out the while loop, the reset light does come on but it still does transmit anything. I think it either may be compiler problems or timing issues. How long must I wait after I reset to start transmitting anything? I've looked in cirrus's 8-bit application note for transmitting and I've read the data sheet for transmitting many times (section 5.7). Im really stumped so any help will be appreciated.
