I almost forgot about that, as its not quite as obvious.  I remember now, a 
long time bike finding that tidbit for some reason.  Must have quickly forgot 
about it after my problem went away.  hehe.

However, like you I would suggest staying with the distro's method of Dev ID 
if possible.  However, I've never had a distro blow up my regular partitions 
because it was trying to turn on the swap, unless you have some command that 
forces the particular partition in the config to be a swap partition (by 
running mkswap, which would not be wise).  Normally It should recognize that 
partition A is not a swap partition, as Nigel's case bears out.
