Why?
The OP said you _should_ put logical partitions in hda4, and I agree.

Disk Druid didn't used to allow you to add a further primary partition
once you had added an extended partition - 
I don't know if that is still the case.
I iaagine your method would cause chaos if you deleted a logical partition.

I came across this with RedHat 9 a year or so ago.
I had sda15, and the system objected.
When I enquired (I had 3 months free advice)
I was told that RH only allowed 15 partitions.
I tried pointing out that 15 is <=15, but didn't get anywhere.
When I got rid of sda15 the problem went away.
I must say I thought this was a RedHat rule rather than Linux.
