i guess so too!
I just wanted to know if anyone tried to circumvent the gas 64kb limit this
way. As i've now understood, it's for my pc-bios-project certainly of no
use because it would be too much overhead to switch to setup this mode
for each bios entry (at runtime). Therefore i try to patch ld or write
my own little one.

Thanks for the replies!
