HT1000 Crash dump failure

[Barney Cordoba]

I'm not sure how best to fix it, but it seems that
this broke crash dumps on 
the HT1000 chipset: 
exit1() at exit1+0x39d 
sys_exit() at sys_exit+0xe 
ia32_syscall() at ia32_syscall+0x256 
Xint0x80_syscall() at Xint0x80_syscall+0x5d 
Uptime: 5d0h51m55s 
Physical memory: 4084 MB 
Dumping 325 MB:ata2: FAILURE - oversized DMA transfer
attempt 65536 > 64512 
ad4: setting up DMA failed

I'm guessing that the atadev->max_iosize is still set
to 64k somehow (DMA 
default) for the ata disk when it does the check in
ad_strategy(), but I'm 
not sure how as for the HT1000 chipset at least
ch->dma->max_iosize is set to 
63k in the controller allocate routine which should be
run before the child 
disk devices are probed and attached AFAICT.

I found this message, but no resolution. Has anyone
figured out how not to get the oversized DMA error
with HT1000 chipset?
