evdev is completely unrelated to CD writing.

Because you're lacking the kernel support for it, see below.

No, it's not.

OK, let's look at the interesting parts:

So you need CONFIG_SATA_AHCI=y, which you have.

For this you need CONFIG_PATA_JMICRON=y, which you don't have. This is where
your CD drive is connected to, right?
Let's go through the kernel config:
> # CONFIG_PCIEPORTBUS is not set
You really need to enable this (that is a PCI-Express machine, isn't it?).
> CONFIG_BLK_DEV_FD=y
Do you have a floppy drive, still?
> CONFIG_HAVE_IDE=y
Useless.
> # CONFIG_CHR_DEV_SG is not set
As written before: No SG, no write (to CD).
> # CONFIG_ATA_SFF is not set
You need to enable this to make CONFIG_PATA_JMICRON visible.
HTH...
