[opensuse] Does YAST's failure to mount Vista/W7 shares 'ro' by default cause problems with BCD on dual-boot boxes?

I have a dual-boot box with 11.4/vista where vista seems to lose the ability to boot regularly (I know its' vista... but read on). Part of the issue seems to center around the way vista and w7 BCD bootmgr use disk signatures as validation of the boot environment during startup. I suspect any change to disk content between windows boots results in boot failure. The vista fail to boot happens regularly requiring the familiar dvd boot and repair.
Looking at the fstab defaults for the normal opensuse /windows/C mount point, I was surprised to find that the partition is NOT mounted ro by default. The default fstab entry is:
/dev/disk/by-id/ata-WDC_WD6400BEVT-00A0RT0_WD-WX40A9996688-part2 /windows/C ntfs-3g users,gid=users,fmask=133,dmask=022,locale=en_US.UTF-8 0 0
I don't know. Maybe the ntfs-3g mount type includes a default 'ro' option, but I've changed the mount to explicitly include ro:
/dev/disk/by-id/ata-WDC_WD6400BEVT-00A0RT0_WD-WX40A9996688-part2 /windows/C ntfs-3g users,gid=users,fmask=133,dmask=022,locale=en_US.UTF-8,ro 0 0
Could failing to explicitly mount the ntfs-3g share ro cause changes that impact the disk signature of the vista/w7 BCD bootmgr that render windows unable to boot?
I don't know. That's why I'm putting this out to the folks that know more about the mount defaults to think about. If it is possible, then the simple inclusion of an explicit 'ro' option mounting windows shares may be warranted. I don't know if it will fix it, or make a difference, but something is causing win boot problems on dual-boot boxes with the windows BCD and bootmgr.
What say the experts?
