Can't burn with ahci(4) and cdrecord

[David Demelier]

Hello,

I tried to burn a little iso with ahci(4) instead of old ata drivers and 
it fails to burn with :

markand at Melon ~ $ sudo cdrecord downloads/ubuntu-10.10-desktop-i386.iso
cdrecord: No write mode specified.
cdrecord: Assuming -sao mode.
cdrecord: If your drive does not accept -sao, try -tao.
cdrecord: Future versions of cdrecord may have different drive dependent 
defaults.
