I have used your SystemAce patch with linux-2.6.16-2. The kernel gets 
loaded with the ace module and is fine.
I want the driver in polling mode. So i have commented few lines related 
to interrupt in the adapter.c file- xsysace_init function.

When i give the fdisk command, it gives few errors and then enters to  
the  fdisk commad promt. It prints the partitions, etc.

But when  i try to quit from the fdisk, it hangs. I am not able to 
complete the request properly (i guess in xsa_thread function in 
adapter.c file)

The dump is as follows:
SystemACE: Error 1 when reading sector 60.
end_request: I/O error, dev xsa, sector 56
SystemACE: Error 1351 when reading sector 62.
end_request: I/O error, dev xsa, sector 56

Command (m for help): p

Disk /dev/xsysace: 512 MB, 512483328 bytes
16 heads, 62 sectors/track, 1009 cylinders
Units = cylinders of 992 * 512 = 507904 bytes
 Device Boot Start End Blocks Id System
/dev/xsysace1 1 1009 500433 6 FAT16

Command (m for help): q
-------
The fdisk enters into xsysace_ioctl function but no commands are 
implemented in the ioctl function and returns an error.

Please help me in this issue and let me know if any other details required.

Thanks
Sudheer
