OpenBSD on Sun Netra X1

[Christopher Intemann]

Hi,
does anyone here have experience with OpenBSD on a Sun Netra X1 server?
I read somewhere that it does only support hard drives up to 137GB of size.
Is there any way to avoid this restriction?
I read somewhere (else) that using a PCI-IDE controller could do the trick.
However could not find any information if I could boot from discs connected
via a PCI-IDE controller.
Any hints?
Thanks,
 Chris
