Kernel Question

[Jon Dixon]

Since using Hoary, I noticed that the DMA for my DVD/CD-RW was not 
enabled by default.

Editing /etc/hdparm.conf to enable the DMA results in a message stating 
that /dev/hdc doesn't exit, yet it obviously does.

The I recalled a setting in the kernel config, so I took a look and found:

CONFIG_IDEDMA_ONLYDISK=y

As I didn't need to play with DMA in Warty, is this something that was 
introduced?

What's the best way for me to fix this, keeping in line with the 
distribution model?

Appreciate any thoughts,

Jon
