In general, I like your proposal.

Regarding the code:
1) What's TV_SEQ_CONTINUE good for? It seems to be unused.

2) Like Christophe I'd prefer to use DTV_ and dtv_ prefixes.

3) Did you mean p.u.qam.modulation below? Also, p.u.qam.fec_inner is
missing.

+		printk("%s() Preparing QAM req\n", __FUNCTION__);
+		/* TODO: Insert sanity code to validate a little. */
+		p.frequency = c->frequency;
+		p.inversion = c->inversion;
+		p.u.qam.symbol_rate = c->symbol_rate;		
+		p.u.vsb.modulation = c->modulation;

4) About enum tv_cmd_types:

SYMBOLRATE -> SYMBOL_RATE?
INNERFEC -> INNER_FEC (or FEC)?

The Tone Burst command got lost (FE_DISEQC_SEND_BURST). How about
TV_SET_TONE_BURST?

FE_ENABLE_HIGH_LNB_VOLTAGE got lost, too.

Which old ioctls should be considered as obsolete? Do you plan to add a
tv_cmd for every old ioctl?

Regards,
Andreas
