You are correct WRT libsmbios. For hapi, I've cc'd Doug who can tell
you about their code. I've done a quick grep of their code, and the
paths above look like the same ones he is using, but I could be wrong.

hapi/apilibrary/dchbas/linux/umhbaslx.c:#define
HBAS_RBU_SYSFS_NEW_DATAREAD_PFNAME		"/sys/devices/platform/dell_rbu/data"
hapi/apilibrary/dchbas/linux/umhbaslx.c:#define
HBAS_RBU_SYSFS_NEW_IMAGETYPE_PFNAME		"/sys/devices/platform/dell_rbu/image_type"
hapi/apilibrary/dchbas/linux/umhbaslx.c:#define
HBAS_RBU_SYSFS_NEW_PKTSIZE_PFNAME		"/sys/devices/platform/dell_rbu/packet_size"
